Governor and grand secretary is known as a grand secretary who also serves as a local governor. As the reform and innovation of the system of grand secretaries by the Yongzheng and Qianlong Emperors, the governor and grand secretaries first appeared in the late years of Yongzheng period, and they were active in the middle and late Qing dynasty. By analyzing the information of 12 governor and grand secretaries in Qianlong period, including their employment background, official career and on-duty information, this group turned out to be a high-quality bureaucratic group with outstanding ability, great military achievement, and abundant experience. They were the division and extension of imperial power, and played an important role in stabilizing the inner court and the outer court.

The Wanhsien Incident was an event where the British gunboat bombed Wanhsien County on September 5, 1926. The people of Wanhsien suffered the tragic loss of life and property due to the atrocities of the British Army, but they did not receive any apology or compensation. The British, on the other hand, believed that the purpose of its action was legitimate, which was to save the innocent vessels detained, punish the tyrannical Chinese army and protect the interests of the British people. The mentality and behavior of the British Navy before, during and after the Wanhsien Incident were all the results of its "Gunboat Policy". However, the surging movement of boycott against Britain from all over China after the incident also made Britain pay the price for its "Gunboat Diplomacy" and prompted a shift in Britain's policy towards China.

The historical initiative spirit is the character refined in various historical periods when the CPC led the people to work tirelessly to change the destiny of the nation and the country, is the spiritual key to continue the great rejuvenation of the Chinese nation, and is the logical starting point that conforms to the core values of socialism for the new era youth. The historical initiative of young people in the new era is based on the theory of critically inheriting historical materialism, nurtured on the cultural keynote of China's excellent traditional culture, and born in the historical endurance struggle. The historical initiative spirit and the unique value of ideological and political education of young people in the new era are explored, which are mainly manifested in the cognitive aspect of deepening the quality of historical materialism, the belief aspect of casting historical confidence, and the practice aspect of enhancing historical initiative. In view of this, young people in the new era must strengthen their theoretical abilities and promote the unity of knowledge and practice, learn from models and establish lofty ideals, adhere to the original mission and enhance responsibility, and make good use of historical methods to promote integrity and innovation.

Against the background of the comprehensive implementation of the rural revitalization strategy, the spatial aggregation characteristics of sports intangible cultural heritages in the Dabie Mountains are studied, aiming to inherit the good traditional culture of the Dabie Mountains, promote the revitalization of rural culture, and consolidate and expand the achievements of poverty alleviation. The spatial distribution, aggregation characteristics and influencing factors of 38 sports intangible cultural heritages in Dabie Mountains were analyzed by GIS spatial analysis method. The results show that: different levels of sports intangible cultural heritages in Dabie Mountains show uneven distribution in different counties; the types of sports intangible cultural heritages in Dabie Mountains are mainly folk entertainment items; the spatial distribution type is cohesive, forming a high-density core circle of sports intangible cultural heritages centered on Shenqiu County and a low-density circle with Shou County, Yuexi County and Lixin County as the center; the quantity, level, type and aggregation law of Dabie Mountains sports intangible cultural heritages are affected by the local geography, historical culture and socio-economic factors.

The paper constructed coupling evaluation index system of rural vitalization and rural tourism. Based on the data from 2013 to 2020, the spatio-temporal coupling development characteristics of rural vitalization and rural tourism in Anhui Province were analyzed by means of the coupling coordination model. The results show that the comprehensive development level of rural revitalization and rural tourism is on the rise, and shows regional imbalance. Since 2016, rural revitalization has played a leading role in rural tourism. In terms of time, the coupling degree of the two systems has gone through three stages of near maladjustment, good coordination and high-quality coordination. At present, the coupling correlation is strong, and the coupling coordination degree has gone through five stages of moderate incongruity, approximate coordination, primary coordination, intermediate coordination and good coordination. The coordination degree needs to be further improved. In terms of space, affected by such factors as location conditions, socio-economic level and cultural heritage, the coupling degree and coupling coordination degree of the 16 cities in Anhui Province show a spatial distribution pattern in which the central and southern regions are higher than the northern region, with obvious spatial differentiation. In the future, it is necessary to comprehensively consider the factors including resources, industry and culture of each city to promote the coordinated development of the two systems.

The legend of Stealing Peach, is the only work recorded in history by Wu Xiude, a composer from southern Anhui in the late Ming Dynasty. The drama presentation of Dongfang Shuo's story has the overall characteristics of both seriousness and melodrama, which reveals Wu Xiude's own literati mentality of respecting ancient history, questioning fame and advocating chivalry. When Wu Xiude is placed in the overall context of the opera artists in southern Anhui in the late Ming Dynasty, it can be found that there are many similarities in their creation styles, which is closely related to the social background of the late Ming Dynasty and the cultural environment in southern Anhui.

In order to solve the problem of high omission ratio of small target objects in remote sensing image object detection, this paper puts forward a small target detection method EfficientNet-YOLOv3 for remote sensing images requiring higher detection accuracy. The method, based on YOLOv3, uses EfficientNet-B0 network to replace the backbone network of the original YOLOv3 algorithm, which can extract image features more effectively, increase the size and number of prediction branches and optimized prior boxes, and improve the detection effect of remote sensing small targets. At the same time, DIoU is selected as the loss function to improve the efficiency of target detection box regression and reduce the omission ratio. Experimental results on DOTA remote sensing image dataset show that the mean average precision mAP of the proposed algorithm is 91.01%, which is 11.82% higher than that of the original YOLOv3. Therefore, it has higher detection accuracy

The phenomenon of college students' star worship presents a complex picture of multiple integration. The research shows that star worship presents the characteristics of high involvement, symbol consumption and rationality, and leads to the problems including deviation of value orientation in the media field, the "materialization" of stars bringing false demand and false experience, and "pan-idolization. This phenomenon is the result of the combined effects of the "migration" and "compensation" needs of fan groups, the connected supply of culture and consumption, and the integration of capital and media. On the one hand, star worship provides new thinking for fans' awareness, star role expectation supply, social interaction radiation range and identity construction; on the other hand, it brings more risks to the dissemination of mainstream values, the "soft binding" of the moral system, and the division and conflict of discourse. To strengthen the quality education of college students, purify the network media ecosystem, and give play to the role of stars as the "construction force", is a reliable way to enhance the positive functions of star worship and avoid its negative influence.

Based on the perspective of planning behavior theory, starting from the trainable political skills, this study explores the impact mechanism of employees' political skills on promoting their active boundary spanning behavior through 234 research samples from 12 enterprises. The results show that employees' political skills have a significant positive impact on boundary spanning behavior; the boundary spanning efficacy plays a partial intermediary role between political skills and boundary spanning behavior; employee power distance negatively regulates the relationship between their political skills and boundary spanning efficacy, and negatively regulates the intermediary role of boundary spanning efficacy between political skills and boundary spanning behavior. The research results can enrich and expand the relevant research on political skills and boundary spanning behavior, and can provide insights on how to encourage more boundary spanning behavior in organizations.

The different English versions of Wang Yue can meet the reading needs of different reader groups. Based on three English versions of Wang Yue, drawing on the Prototype-model Translation Theory, this paper introduces the translation concepts of "fitness" and "faithfulness" and readers' satisfaction, and reaches the following conclusions by using the research method of translation comparison: Xu Yuanchong's version can meet the reading needs of professional readers; Sun Dayu's version can meet the reading needs of non-professional adult readers; The version by Stephen Owen can meet the reading needs of non-professional children readers. Therefore, the article holds that only by using appropriate translation strategies to faithfully translate the writing features of the source text, and only by "adapting" to the reading needs of different reader groups, can different versions coexist because they fit the reading needs of different readers.

In the new era, people's demand for a better life is increasing, and they have a deeper understanding of physical exercise and physical health. Their desire to improve their health has reached an unprecedented level. With the research methods of literature review, saturated experience, questionnaire survey and case analysis, the study surveyed 842 rural elderly people and 163 township cadres in Anhui Province, and the results show that: There are problems in the governance of sports public service for rural elderly people, such as equalization imbalance, lack of basic guarantee, and lack of people-oriented services. Based on this, this paper puts forward relevant suggestions: balancing the supply of rural elderly sports public service, consolidating the basic guarantee of rural elderly sports public service, and clarifying the people-orientation subject of rural elderly sports public service. To comprehensively improve the development concept of sports promoting health, implement the system of balancing the supply and demand of elderly sports public service, strengthen the support and implementation of elderly sports public service policies, improve the matching of various human resources, and build a higher-level rural elderly sports public service system, are the primary task to carry out the national fitness strategy and meet the health needs of all the people.

The drastic change from the Ming to the Qing dynasty profoundly affected Gu Zhenli's Ci-poetry creation, which were delicate words at the end of the Ming Dynasty, and gradually changed from expressing the severe pain of losing the country in the early Qing Dynasty to encouraging brothers and nephews to seek an official rank, reflecting the complex and subtle mental journey of female writers in the early Qing Dynasty. In addition, unlike other female writers who mostly follow the tradition of feminine Ci-poems, Gu Zhenli was more closely connected with the early Qing Ci-poetry circles. She was a member of the Liangxi Ci-poet group, and was influenced by the Huajian Caotang group; her refreshing style also echoed the "Jiaxuan Feng" group and Yangxian school, showing the uniqueness of Gu Zhenli忆s mentality and creation as a female Ci poetess.

The Healthy China strategy is a vivid practice of Chinese modernization in the field of health. A healthy family is the social foundation of a healthy China. The fundamental goal of building a healthy family is to cultivate a civilized and healthy lifestyle, and to promote a civilized and healthy family as the starting point of a healthy China. The practice requirement of family civility enabling family health is to pay attention to the building of family tradition: to carry out healthy family education, and let the healthy China strategy and the patriotic health movement carry forward in all families; to promote healthy family traditions and make a civilized and healthy lifestyle a daily habit of families; relying on the strength of the family, we should promote the establishment of civilized families and healthy families at the same time, so that family civility and family health can develop in the same direction.

After the 21st century, due to the huge social changes in China, there are various uncertainties. While enjoying the achievements of social development, we are also facing a large number of potential social risks. Resilient cities and community resilience can effectively cope with risks, improve the level of governance, and promote urban development. This paper takes the rainstorm and flood risk of W community in Chaohu City as an example to analyze the resilience construction of W community from three aspects of economic development, social capital and community capacity from the perspective of resilient city. The study found that the development of economy, social capital and community capacity plays an important role in improving the stability, recovery and adaptability in coping with disasters, and as a result of community resilience construction, it can build a "resilient city" from the four dimensions of environmental resilience, institutional resilience, community resilience and individual resilience, and improve the modernization level of urban safety governance.

Taiping Guangji cited numerous stories from Youyang Zazu. By taking the cited Youyang Zazu Nuogao Ji as an example, the variant characters can be divided into three parts: variant characters, ancient and new characters, substitute characters, and regular and popular characters. For variant characters, Taiping Guangji often presented a complicated usage where two words are interchangeable and slightly different; for ancient and new characters, Taiping Guangji had both ancient and new characters, but the new characters were adopted more frequently; for substitute characters, Taiping Guangji tended to avoid such characters and pursued accuracy; for regular and popular characters, Taiping Guangji tended to use regular characters.

Based on 16 municipal panel data of Anhui Province from 2015 to 2020, this paper uses the hierarchical analysis—entropy weight method to construct a regional innovation evaluation system, characterizes the level of high-tech industry agglomeration by location entropy, and then empirically analyzes the interaction between regional innovation system and high-tech industry agglomeration. The results show that: the differences in the trends of the concentration of high-tech industries and the differences in the comprehensive scores of regional innovation systems in Anhui Province are generally consistent, and there is a Granger causality relationship between the two; the spatial distribution characteristic is a decreasing trend in the north-south circle with Hefei and Wuhu as the centre; there is a significant "snowball effect" in the development of high-tech industry agglomeration in Anhui Province; the regional innovation system has a more obvious role in promoting the level of high-tech industry agglomeration than a single indicator; foreign direct investment, the investment in scientific research and the level of economic development all have significant positive effects on high-tech industry agglomeration; but due to the siphoning effect of Jiangsu Province, Zhejiang Province and Shanghai on high-level scientific and technological innovation talents in Anhui Province and the tendency towards the heterogeneous structure of scientific and technological innovation talents, the investment in scientific research personnel cannot play a positive role in promoting the high-tech industry agglomeration for the time being.

Buckwheat was widely cultivated in Guizhou with a unique natural and social environment from the Ming Dynasty to the Republic of China. Through the analysis of historical documents and local chronicles, the paper aims to explore the issue of buckwheat planting in Guizhou during this period. Due to the unique natural conditions of Guizhou and the influence of immigration, political power and the idea of storing up grain against famine, buckwheat was widely spread in Guizhou; its distribution shows an upward trend over time, and its planting area developed in a zigzag pattern over time. For hundreds of years, the values of buckwheat consumption, famine alleviation, cultural and medicinal use have had a profound impact on Guizhou, alleviating its famine, promoting the diversified development of Guizhou economy and enriching the diversity of Guizhou food culture. The study of buckwheat planting in Guizhou from the Ming dynasty to the Republic of China can deepen the understanding of buckwheat planting history in Guizhou, develop Guizhou buckwheat resources, build green and high-yield buckwheat economic belt, develop buckwheat characteristic industrial chain, and provide support for rural revitalization.

By combing 360 judgments on negligent crimes, it is found that the number of cases with civil compensation without probation is much lower than that with other circumstances without probation in terms of mitigating circumstances such as voluntary confession, confession and pleading guilty. Through the data comparison and case analysis of civil compensation and victim (family member) understanding in the application of probation for negligent crimes, we can know that the two have different effects on the application of probation. In practice, the courts overemphasize the existence of civil compensation, so there exist problems of simplifying the identification of probation application for negligent crimes. The orientation of civil compensation affecting the application of probation should be a formal exterior of the penitent psychology of the defendant, rather than the substantive connotation. The court cannot judge whether the offender repents only by whether the offender has compensated, but should examine the offender's compensation ability and performance afterwards, and comprehensively determine whether the offender repents and whether probation can be applied.

Xi Jinping's Thought on Ecological Civilization is the latest theoretical achievement of contemporary Marxism. It creatively develops the Marxist ecological theory, profoundly reflects the progress direction of the new form of human civilization, and strengthens the self-confidence of the Chinese-style modernization path. It is a powerful weapon to guide the construction of China's ecological civilization. Anhui unswervingly follows Xi Jinping's ecological civilization thought for the modernization of ecological governance. The fundamental position of Anhui's ecological governance modernization is established with Xi Jinping's ecological civilization thought, which nurtures the generation path of Anhui's ecological governance modernization, highlights the key steps of Anhui's ecological governance modernization, and facilitates the modernization of the national governance system and governance capacity.

Finally, it explores the differences in effect of digital inclusive finance on SMEs among industries and regions, and conducts heterogeneity analysis. The results show that: firstly, digital inclusive finance plays a significant role in promoting the sustainable development of SMEs, more than 50% of which have been indirectly affected through easing financing constraints; secondly, through the heterogeneity analysis, it is found that the development of digital inclusive finance plays a stronger role in promoting enterprises, Internet and computer industry in western China. This paper provides enlightenment for the formulation and implementation of digital financial inclusion policies.

The introduction of potatoes in Shaanxi has regional independence, with different channels of introduction in northern, central, and southern Shaanxi, showing multiple sources and stages. The potato terms in northern Shaanxi have three categories: "Shanyao"(yam) type; "Yangyu" (foreign potato) type; "Manjing" (vine tuber) type. Among them, the "Shanyao" type in northern Shaanxi is related to the northwest land trade; the "Yangyu" type is related to its introduction in central Shaanxi; and the "Manjing" type is the result of self-innovation. The "Manjing" type in northern Shaanxi has no historical connection with the "Manjing" terms in southwestern and southeastern Shanxi, which is a coincidence result of parallel evolution. The "Yangyu" type in central Shaanxi is related to the spread of potato varieties along the southeastern coastal areas. The "Yangyu" type in southern Shaanxi has two sources: it spread upstream from the southeastern coast; or it came from the Sichuan and Hubei regions.

In the context of the deep integration of information technology and education, online and offline hybrid flipped teaching has become the norm. The key elements for the effectiveness of online and offline hybrid flipped teaching mainly include: multiple integrated curriculum resources, teaching resonance of students' online independent learning—offline discussion between teachers and students, teaching quality monitoring by the wholeprocess assessment and dynamic adjustment. In practice, online and offline hybrid flipped teaching has problems in its design, operation and monitoring, which affect its improvement of quality and efficiency. The teaching design, operation and quality monitoring of the "Environmental Resources Law" online and offline hybrid course are integrated, resonant, and modified, which can ensure the teaching quality of the course.

The local expression of the rural memorial hall can help promote rural culture, and it is an important part of the local cultural gene translation from the perspective of regional culture. Based on the literature analysis and field investigation of the regional culture of Liu Mingchuan's hometown, this paper uses the method of landscape gene translation to do the design analysis and elaboration. Combined with the Liu Mingchuan Memorial Hall designed by Anhui Urban Construction Design and Research Institute, the design overview is analyzed from three angles: design conception, architectural form and spatial layout. At the same time, three design interpretations are proposed based on the above analysis: design translation expresses the local landscape genes; architecture is integrated in the geographical topography; space conveys the spirit of the times. This provides reference for the construction of rural memorial buildings with regional characteristics and the spirit of the times.

The education informatization has developed rapidly, and the construction and promotion of MOOC has made it a reality to share high-quality education resources. The proportion and advantages of online teaching are particularly prominent, but some problems have also been exposed in its implementation. In view of the problems existing in the teaching of programming courses, the blended teaching for this kind of courses is explored based on the OBE concept. A new blended teaching model based on the principle of reverse design is proposed, which is "Defining learning output—Realizing learning output—Assessing learning output—Using learning output". The main steps of course construction and teaching implementation includes: determining course objectives, determining teaching content, dividing knowledge modules, constructing course resources, designing teaching strategies, implementing blended teaching, and assessment feedback. Practice has proved that the new model based on reverse design can effectively improve the course teaching quality.

With the development of technology, the demand for science professionals is increasing. In the future workplace, workers with a science background will become an indispensable part of various industries. Science students can find employment opportunities in various industries and have a certain competitive advantage in the job market. Science majors typically require high academic performance and professional knowledge. This may be a challenge for students, who need to work hard meet the standards. The competition in the field of science is also fierce, as numerous students choose science majors, resulting in increased competition in the job market. Based on the above situation, through quantitative analysis and literature research, this paper analyzes the current employment prospects for graduates and explores the university student training mode. It discusses the shortcomings in current education, teaching, and employment guidance in universities, and proposes measures of optimizing the curriculum system and strengthening school-enterprise cooperation. The study hopes to promote the reform and innovation of student training mode and improve the level of education.

The sound standing wave experiment is a compulsory part of university physics experiments, but its traditional experimental apparatus is inadequate. The article provides an in -depth analysis of the mechanism and characteristics of sound standing wave generation. We have designed an acoustic-optical conversion circuit, which can effectively and precisely convert the sound standing wave signal into a diode luminescence signal and apply it in a standing wave tube, and we have successfully developed a sound-controlled light-emitting standing wave experimental apparatus. The apparatus not only realizes the organic combination of qualitative demonstration and quantitative measurement of the standing wave phenomenon, but also has the advantages of easy operation, visual clarity, stable operation, and high measurement accuracy. It can also provide important reference for the development of similar experimental teaching apparatus in universities.

The river and lake chief system, a new system that the state values, is helpful in encouraging the management of river and lake pollution, which is crucial in promoting environmental protection. With the increasingly active research on the river and lake chief system and its development, this paper sorts out and evaluates the literature and policies of the definition, construction process and main tasks of this system. Then, based on the panel data of Anhui Province from 2011 to 2021, the relationship between the implementation of the river and lake chief system and the efficiency of water resource utilization is analyzed by SBM model. The results show that the efficiency of water resource utilization in Anhui Province has been significantly improved with the implementation of the river and lake chief system. However, there are still areas worthy of improvement in the implementation of the system. In view of these problems, Anhui should improve the legal construction, pay attention to the preliminary investigation work, and perform well in publicity work to increase the effectiveness of the river and lake chief system.

The traditional requirement modeling method describes requirements through a formal modeling language, which is difficult to adapt to the dynamically evolving requirements in the Cloud ERP domain due to its lack of flexibility and supporting requirement solutions. Aiming at the above problems, a Cloud ERP modeling and evolution method based on the E-CARGO(Environment-Class, Agent, Role, Group, and Object)model was proposed, relying on the feature that E-CARGO can flexibly model the evolving requirements. Firstly, the requirements were deconstructed into needs and Cloud ERP services and described as a role-based collaboration problem, which was then modeled by the E-CARGO model; secondly, in order to conduct more domain-specific assessment of talent competencies in the Cloud ERP domain and to build high-quality Cloud ERP development teams, a fuzzy complementary judgment matrix was established using the Fuzzy Analytic Hierarchy Process(FAHP)to measure talents' comprehensive ability value; finally, the group role assignment method using E-CARGO model combined with CPLEX optimization package was used to obtain the requirements maximization satisfaction scheme in all evolutions. The experimental results show that the proposed method is not only able to model the evolving requirements in Cloud ERP flexibly, but also can find the requirement satisfaction solution in a very short time, and then respond to the evolving requirements quickly and provide Cloud ERP services on demand.

Rural revitalization has provided important development guidance and impetus for rural preschool education. Rural traditional culture such as farming customs has offered rich cultural soil for rural preschool labor education, which is conducive to the high-quality practice of rural preschool labor education. In order to help rural kindergarten teachers to understand the unique value and practical necessity of rural preschool labor education, the study analyzed the value of rural preschool labor education from the perspective of rural revitalization based on literature review and personal observation, and found in practice that there are challenges such as insufficient attention from families, kindergartens, and communities, inadequate practical ability of teachers, weak curriculum construction, lack of local characteristics, and low quality participation of children. In this regard, based on the theoretical requirements of rural revitalization and labor education, and the current situation of rural education, the countermeasures are put forward, so as to provide reference for the implementation of rural preschool labor education with rural characteristics, and provide enlightenment for improving rural education quality.

"Southern Ming"(Nanming) is more than a mere dynastic concept. In the course of its evolution, due to the speaker's stance and purpose, the connotation of "concept" changed many times, and behind the changes were implied the atmosphere of the times, the social value orientation, and the spiritual orientation of the speaker. During the War of Resistance against Japanese Aggression, facing the hardships of his family and the country, Tai Jingnong echoed the "Southern Ming fever" with the title "Zhang Cangshui, the National Hero". But Tai Jingnong's life experience, full of party disputes and betrayals, prompted him to redefine the concept of "Southern Ming" through frequent textual "surgeries". The conceptual evolution history from "Southern Ming" to "Late Ming" to "Demise of Ming" reflects Tai Jingnong's real-life experience of "divergent paths". It also reflects Tai Jingnong's identity anxiety as an intellectual and his fears about the reoccurrence of history. Therefore, the discovery and framing of the historical concept "Southern Ming" in literature from the perspective of conceptual history not only facilitates understanding the narrative choices and technique structures of the writers' creations, but also helps to shed light on the spiritual aspirations and ideological orientations of literati such as Tai Jingnong during the turbulent times.

After the outbreak of the Total Resistance War Against Japan, the eastern coastal areas were largely occupied and the industries in the southeast of China plunged. To meet wartime needs, the Wannan Industrial Company was established as a joint venture between the Economic Commission of the Third Theater and the head office of Anhui Local Bank. The company aimed to promote the development of small and medium-sized industries in the mainland and increase wartime production, thus establishing four factories for tanning, textile, paper, and match making. Under wartime conditions, the company operated with difficulty, but it ensured the smooth progress of its business by shifting its business strategies in a timely manner, implementing centralized procurement and sales of raw materials and products, promoting technological innovation and developing new raw materials, and adopting flexible and diverse production and operation modes. The establishment of the Wannan Industrial Company played an important role in meeting the basic needs of the public during the war and actively supported the War of Resistance Against Japan.

Fishery industry is an important part of the economy of the Chaohu Lake area. Chaohu Lake, rich in fishery resources and having a large number of fishermen, is an important fishing area in Anhui Province. Before the founding of the People's Republic of China, Chaohu Lake was faced with many difficulties in fishery development, such as disordered production, hard life of fishermen and chaotic water security situation. After the founding of the People's Republic of China, the Communist Party of China and the government emphasized the development of fishery, by carrying out democratic reform with the elimination of gangs as the core, promoting the cooperative movement, and improving aquaculture technology, which aroused the production enthusiasm of fishermen improved their lives, and also constituted the valuable experience of Anhui fishery management in the early days of the People's Republic of China.

In the new era, the high -quality development of China's wushu （a martial art） industry is of great significance. With the research methods of literature and logical analysis, this paper studies the high -quality development of wushu industry under the "double cycle" development pattern. The basic logic of the high-quality development of China's wushu industry mainly includes: industrial structure adjustment to promote the balanced development of China's wushu industry; science and technology to promote the innovative development of China's wushu industry; internal and external opening up to promote the global development of China's wushu industry. However, the unsolid foundation of development leads to the imbalance between supply and demand in the development of wushu industry; weak domestic consumption and lack of innovation lead to difficulties in the development of wushu industry; insufficient compound talents causes the development of wushu industry to lack intellectual support; changes in the international situation put obstacles in the way of the wushu industry trying to develop overseas. In order to realize the high-quality development of China's wushu industry in the new era, first, we should consolidate the foundation and promote the balanced development of China's wushu industry; second, we should adopt a multi-pronged approach to promote the innovative development of the domestic wushu market; third, we should work together to train compound talents who can meet the needs of the "double cycle" development pattern; fourth, we should coordinate to promote the overseas development of the wushu industry.

The Yangtze River Delta(YRD) integration strategy has brought new opportunities for the development of rural tourism in Anhui Province, and the development strategy for rural tourism in Anhui Province has been widely discussed during this new development stage. The Delphi-SWOT-AHP model was used to conduct qualitative and quantitative analysis on the strategic positioning of rural tourism development in Anhui Province. 16 factors influencing the development of rural tourism in Anhui Province were identified using the SWOT model. The analytic hierarchy process (AHP) structure model was then built with the Yaahp software to calculate the SWOT development strategic strength and type orientation angles, and the strategic type strength map was drawn. The results show that the development of rural tourism in Anhui Province should adopt a proactive growth-oriented development strategy (S-O strategy). While seizing the opportunity of integrated development of the YRD and promoting multilateral cooperation in rural tourism regions, we should also strengthen the construction of the rural tourism governance system and create distinctive brands of rural cultural tourism to promote the high-quality development of rural tourism in Anhui Province.

Doris Lessing, the Nobel Prize laureate in literature, constructed two different worlds in her science novel The Marriages Between Zones Three, Four and Five: one is an old and wicked world full of darkness, and the other is a new world full of imagination and hope. From the perspectives of utopia and dystopia, this paper aims to explore the author's utopian vision of a good society carried by the dystopian narration of a wicked world, thus revealing Lessing's concern and hope for human civilization and future world.

Offset surfaces are widely used in industrial fields, such as tool path geometry generation and robot path planning in NC machining, surface plate representation in solid modeling, etc. Geodesic, line of curvature and asymptotic curve are three kinds of important characteristic curves which play a decisive role in the properties and shapes of surfaces. The construction of offset surface pencils preserving common characteristic curves is studied, that is, when constructing a surface pencil P（s，t） with a given curve r（s） as a common characteristic curve, the corresponding curve r（s） on the offset surface pencil P（s，t） is the same type of characteristic curve. Firstly, P（s，t）is expressed as the linear combination of the Frenet frame of r（s）, and the coefficients of the linear combination are called the scale functions. Then, P（s，t） is taken as the base surface to construct its offset surface pencil P（s，t）. According to the properties of the characteristic curves, whether r（s） can be guaranteed to be the same type of characteristic curve as r（s） on P（s，t） completely depends on the given curve and has nothing to do with the scale functions. Finally, the cylindrical helix and circle are taken as examples to verify the correctness of the above conclusions.

The implementation of agricultural production responsibility system is the most important economic system reform in rural China after the Third Plenary Session of the 11th CPC Central Committee in 1978, which promoted the liberation and development of productive forces. Wuwei County is located in the Jianghuai area, with a large population and yet inadequate land. During the period of agricultural collectivization, its agricultural development stagnated, so Wuwei County was in urgent need of reform. Wanli went to Wuwei many times to give guidance when he was in charge of Anhui, making Wuwei a pioneer in agricultural production responsibility system reform. Through the investigation and analysis of the evolution process of agricultural production responsibility system in Wuwei County, the paper discusses the attitudes of and measures by the central, provincial and local governments to the responsibility system reform at that time, in order to reveal the complexity and twists of the reform of agricultural production responsibility system in Wuwei County.

As a new field of linguistic research, language landscape is increasingly attracting the attention of more scholars. Language landscape is also an important dimension to reflect the image of a city. Based on the field study of two representative scenic spots in Hefei City—Sanhe Ancient Town and Wanda Theme Park, this paper describes the characteristics of the language landscape by collecting language materials, specifically analyzes the language signs from the perspective of English translation, and then proposes optimization strategies for language landscape translation, with a view to providing reference for the construction of language landscape in Hefei and the standardization of language landscape translation.

In order to improve the profits of enterprises and reduce operating costs, it is necessary to predict the loss of users, and carry out precise marketing in advance to retain users. The XGBoost model is established to train the user churn data, and the importance ranking of input features is obtained. The Top-K feature is selected to obtain a new training set. On the one hand, the XGBoost model of Bayesian optimization is established based on the training set, and the optimal parameters are found by Bayesian optimization; On the other hand, 8 models are selected to construct and verify the model, and the model is evaluated in precision, accuracy, recall and F₁ value respectively. Experimental results show that XGBoost model based on Bayesian optimization has better prediction results and higher efficiency than other models in telecom user churn prediction.

In 1926, after the "Five Provinces Alliance" led by Sun Chuanfang was defeated by the National Revolutionary Army, three remnants of the coalition army passed through or stationed in Huizhou for a period of up to three months, causing a significant impact on the local social order. Huizhou society has suffered the most severe damage since the Xiantong War, which not only has a significant impact on economic development and people's lives, but even the long-standing Huizhou culture has suffered significant setbacks. To this end, local and foreign residents of Huizhou are doing their best to carry out post disaster reconstruction work, while also calling on all parties to intervene in negotiations with Sun Chuanfang to minimize losses. The military disaster in Huizhou from 1926 to 1927 reflected the impact of the Beiyang warlords on traditional society under the changing social order, and also reflected that the Beiyang army, which could not protect the environment and the people, was inevitably eliminated by the revolutionary forces formed by the revolutionary army and the righteous people.

This paper studies the optimal reinsurance-investment strategy of insurance companies and reinsurance companies aiming at maximizing the common interests of insurance companies and reinsurance companies under the Heston model in which the price of risky assets obeys the Heston model in the financial market environment considering bond defaults. According to the CARA utility function, the corresponding HJB equations are established for the pre-default case and post-default case, and finally the relevant parameters are analyzed for the optimal reinsurance-investment of the two companies. The results show that the relevant parameters in the Heston model have a certain impact on the investment of insurance companies and reinsurance companies in risk assets and defaultable bonds.

With the development of capital globalization, network communication based on big data Internet technology has become a new form of human communication. College students are among the main users of the Internet. In the network communication, there have been dishonest behaviors such as forging false identity through the network, abuse of network service convenience, materializing oneself to gain traffic, and academic misconduct, which have brought new challenges to the growth and development of college students. From the four aspects of enhancing college students' awareness of network integrity, strengthening the construction of network supervision mechanism, regulating the live communication process, and improving the college integrity education mechanism, this paper explores the path to reduce college students' network dishonesty, which can help regulate and guide college students' network behavior, thus promoting the independent, equal and healthy growth of college students.
