In the era of social media, the popular Internet memes change rapidly. Behind the Internet carnival, problems such as the rampant internet violence and the expansion of language gap between different groups have emerged. The rise and decline of "six learning" meme completely presents the communication life cycle of a popular network meme. Taking "six learning" as the starting point, this paper analyzes the meme fission communication and audience-oriented communication characteristics of the popular Internet meme. Focusing on the hidden problems exposed in the process of network meme communication, this paper puts forward solutions from three aspects: new media, KOL ecology and the new and old discourse system, in the hope of improving the network public opinion environment.

During the period of the Republic of China, banditry was a serious problem in Northern Anhui. Under the guidance of the correct policy of the Central Committee of the Communist Party of China after the liberation, the grassroots organizations in Northern Anhui were established to cooperate with many other regions and cooperate with other public security campaigns. Public security organizations had been widely established to maintain local security. In the process of suppression, the masses had been actively mobilized and educated, so the criminals had no place to go. With the joint efforts of the government and the people, the success of banditry suppression in Northern Anhui was remarkable. By 1952, the bandits in Northern Anhui were basically cleared, which ensured the smooth progress of all work.

For the new coronavirus epidemic situation, our government decisively exercised the administrative emergency power and initially restrained the development of the epidemic situation. In order to ensure the safety of people's lives, the strict control measures adopted in this epidemic reached an unprecedented level. Many scholars pay attention to the problems in the exercise of administrative emergency power, especially the restrictions on civil rights. Some scholars dispute the legitimacy and rationality of the control measures. Based on the analysis of the basic principles of administrative law, it is found that the crux of the dispute lies in the imperfection of the legal system of emergency state, the lack of supervision of the normative documents of administrative emergency and the judicial incoordination in the regulation of administrative emergency power. These disputes can be resolved by improving the legal system of emergency, giving full play to the supervision role of the constitutional review system and clarifying the standards of judicial review after the event.

With the widespread mobile terminals and the speeding of Internet, short online videos have become an important new media reporting method in the development of media convergence with the advantages of visualization for audience, fragmentation in social contacts and diversity in contents. The development of short online videos has also exerted a tremendous influence over news spreading, which results from the great changes of news spreading practices caused by the spreading feature of online videos and its combination with news spreading's inherent law. Among those reports of COVID-19, in order to meet the information needs of the public, short online videos have revolutionized the reach of public opinion influence, the means and contents of public scrutiny. Under the new media context, the short online videos have played a fundamental role in public opinions. Through good use of short online videos, gradually reforming transmission mechanism and improving the technology, the authority, the folks, the mainstream media and socialized media can realize public opinion resonance, to achieve information disclosure, guidance and supervision of public opinion, humanistic care and popularization of knowledge. 

City cultural brand is an important manifestation of the city忆s core competitiveness. It is an inevitable requirement for cultural brands to promote the coordinated development of city economy and society. With the increasingly fierce competition between cities, the construction of Hefei city cultural brands has attracted the attention of city managers and academic circles. On the basis of literature review, this paper analyzes the background of Hefei city cultural brand construction from the aspects of economy, society, culture and policy,exposes the main deficiencies through questionnaires, puts forward the positioning orientation of a famous city with the Chaohu Lake, filial piety, integrity, innovation, and puts forward reasonable suggestions on utilization of city resources, brand building content, brand communication and maintenance, in order to provide reference for the research and practice of city cultural brand building.

Under the influence of the COVID-19 epidemic, the employment of college graduates is facing three pressures: the continuous increase of the number of graduates, the decline of social economy and the epidemic situation. In a certain period of time, the number of people losing jobs will be increasing, and the demand of the employment market for new graduates is greatly reduced compared with the same period last year. In the process of graduates’ employment, colleges and universities should actively explore a new mode of work from "offline" to "comprehensively online", change the traditional "face-to-face" centralized guidance, improve the "personalized" employment guidance rate, and pay attention to the change of "close relationship" of graduates. Facing the new changes in employment, universities should change employment guidance thinking and explore the new mode of "Internet plus employment", build a network service platform to realize the network operation of employment, pay attention to the online employment safety and improve graduates’ ability to guard, pay attention to the psychological problems in the employment process and open up new channels for network counselling, strengthen the support for key groups and improve the tracking guidance, so as to promote the steady development of graduates’ employment and guarantee the employment service for graduates.

The increasingly frequent films and television programs exchanges between China and foreign countries have highlighted subtitles translation. In recent years, there has been a clear tendency of entertainment-oriented rewriting in subtitles translation, especially in some English commercial films and dramas. This paper analyzes the entertainment-oriented rewriting in subtitles of Spider-Man: Homecoming. Through the analysis of reasons for rewriting and the phenomenon of improper entertainment-ori- ented rewriting in the Chinese version, this paper provides some reference for entertainment-oriented rewriting on the subtitles translation, aiming to promote film translation from English to Chinese.

In recent years, against the background of building cultural confidence, traditional Chinese medicine cultural documentaries are flourishing. Traditional Chinese medicine culture documentaries with different emphases depict the important influence of traditional Chinese medicine culture on Chinese people in an all-round and threedimensional way, and construct the identity of traditional Chinese medicine culture in line with the current situation. From the perspective of cultural memory, this paper observes the strategies of constructing imaginary space, meaning presentation and identity construction in narrative framework, narrative perspective, ritual tradition,memory field and other aspects of traditional Chinese medicine cultural documentaries, which provides new possibilities for the writing of traditional Chinese medicine cultural documentaries and even the self-transcendence of traditional Chinese culture documentaries. From the perspective of cultural memory, traditional Chinese medicine cultural documentary gradually becomes an expression mode and writing mode of traditional cultural documentary,or has the vitality of cultural construction and the potential of value production.

It is a vital part and important task to strengthen the ideological and political education of college students for colleges and universities to deal with public health emergencies. In the prevention and control of COVID-19, the effective practice of fighting against COVID-19 across the country has provided rich materials for the ideological and political education of college students. In the situation of regular epidemic prevention and control, it is of great value and significance for colleges and universities to improve the effect of ideological and political education of college students and fulfill the fundamental task of cultivating people with moral integrity by exploring the effective path and mechanism of integrating the pandemic prevention and control into ideological and political education of college students. It is advisable for universities to boost the ideological understanding with the focus on the measures for fulfilling the task. It is essential to combine direction and value, link dominance to regularity, and mix theory with practice. Coordinated efforts should be made to combine the pandemic prevention and control with ideological and political education. Ideological and political education of college students will be truly made the ideological driving force and motivation for the prevention and control of the pandemic.

The "collision" between the COVID-19 epidemic and the spring recruit, which is the highlight of college graduates' job hunting, has extremely adverse effects on graduates忆 employment. By investigating the impact of COVID-19 epidemic on the employment opportunities, employment costs, employment channels, employment mentality and employment quality of Anhui college graduates in 2020, this paper makes an objective analysis from three dimensions: government agencies, schools and students, so as to accurately grasp the employment cognition, employment dynamics and employment status of college graduates during the COVID-19 epidemic. The aim is to improve the job-hunting strategies of college graduates under the normal epidemic prevention and control, enhance the effectiveness of employment work, and provide guidance for the introduction, convergence, revision and precision of employment policies.

In the Qing Dynasty, Hanshan Qingshi, a typical family of imperial examination officials, rose in the local area. In the family, Zhang huanxin, Qing fengting, Qing fenghui and Qing peiyun were all well-known for composing poems, which made Qingshi family more famous. Along with the influence of geography, times and family traditions, it was their good family tradition that made their culture of talented ladies rise through time. The two aspects influenced promoted each other, forming a benign interaction. A case analysis of the family's tradition and culture of talented women can help understand the internal mechanism and reasons for the prosperity of the culture of talented ladies in the traditional family, and further deepen our understanding of the culture of talented ladies in the region around Chaohu Lake.

The whole society of Tang Dynasty attached great importance to education, and the imperial family was no exception. In addition to emphasizing the education of princes and kings, the princesses of Tang Dynasty also received good family education. The family education of Tang Dynasty princesses represents the highest level of women’s family education in Tang Dynasty. They have special learning institutions and female teachers to carry out daily education for them. The contents of education cover etiquette, calligraphy, art and poetry. With the rise and fall of the country and the development of society, the Tang royal family忆s educational concept for princesses has also changed, and princesses in different periods have very different "portraits" for their groups. On the whole, many of them have excellent cultural and artistic qualities and have written their own splendid chapters in history books.

The Tangshan mine disaster in 1920 was the most serious coal mine gas explosion in modern China. It not only caused heavy casualties and property losses, but also triggered a strong response from the public. As an influential public safety incident, the occurrence and resolution of the accident was not purely technical problems; it was closely related to the management system of the mining bureau, the government's attitude towards mining labor and the supervision of public opinion. The research can reveal the difficult position of modern north China miners, and provide a new perpective for the study of modern workers' movement.

The interactive influence of politics and education is reflected in the evolution of primary school layout in Hefei County in the early period of Nanjing National Government（1927—1931）. Under the "province-prefecturecounty" three-level administrative division of Beiyang Government（1912—1928）, there were at least 100 primary schools in Hefei County. Their urban-rural ratio was about 29.9%, and their ownerships were complicated. After the establishment of Nanjing National Government, the local political structure was re-established. In this context, the number of primary schools in Hefei County was reduced to 67, and the urban-rural ratio of primary schools was increased slightly; there was a trend of primary schools becoming public schools, but the actual situation was still complicated. During this period, many primary schools formed school districts, and different school districts formed local educational administrative divisions in Hefei County, which became the basis of local administrative divisions in Hefei County, and directly affected the local administrative structure of Feidong, Feixi and Changfeng counties.

"Wuchang Taiping Lantern" is one of the main types of the national intangible cultural heritage "Dongzhi Lantern". It has a long history and rich meanings. It integrates the original cultural symbols such as folk songs and dances, original crafts and religious beliefs. It embodies the collective memory of the local people and reflects the spiritual outlook of the working people. The research on "Taiping Lantern" takes into account both diachronic and synchronic perspectives. On the one hand, through the description of "space", the research explores its historical origin and reveals its spatial state and regional structure of occurrence and development in "change" and "invariance"; on the other hand, its deductive form is interpreted to decipher the multicultural connotations contained therein, and identify the "idol" and "reality" according to the universality of the ritual, which is beneficial to the exploration of inheritance and the protection of the regional and minority intangible cultural heritage represented by the "Wuchang Taiping Lantern".

Fan Zeng was a famous politician and military strategist in Chinese history. He experienced the transition and transformation of Chaohu Basin from Chu culture to Han culture. Through a comprehensive study of the literature on Fan Zeng, it is found that Fan Zeng is a tyaical figure with rich connotations of ancient Chinese culture. It can become an important cultural resource for Chaohu City in inheriting the characteristic regional culture, carrying forward the traditional spirit, and building a good city image. It is a rational choice for Chaohu City to develop cultural tourism, enhance the city image and boost the local economy by taking Fan Zeng cultural resources as the main body, integrating all the cultural resources of Chu and Han in the city, and building a Fan Zeng cultural park with rich content, diverse functions, reasonable layout and obvious characteristics. At the same time, it can also promote people's commemoration of Fan Zeng, and carry forward his traits of patriotism, homesickness, loyalty, integrity and tenacity. The construction of Fan Zeng Cultural Park should reflect the background of Chu and Han culture, and always bear the theme connotation of Fan Zeng Culture. The cultural park should be planned and designed as a whole with five functional areas: background cognition area, sacrifice memorial area, situational experience area, Han tomb viewing area and product creation area, so as to make it a well-integrated whole.

The academic world has been utilizing modern western semiotics to interpret art for a long time, mainly focusing on art history and art criticism as well as ontology research of Western painting. There are only a few interpretations and researches on traditional Chinese painting. As a painting geezer in the late Ming and early Qing dynasties, Chen Hongshou has left a large number of figures, flowers and birds, and landscape paintings for the world. His works are of a unique style and enjoy a high reputation in the history of Chinese and foreign art. To some extent, his painting works have many similarities with the theory of "three Symbols and three Terms" (icon, index, symbol, representamen, interpretant, object) put forward by American semiotician Pierce. Based on Pierce's semiotics, this paper makes an in-depth analysis and interpretation of Chen Hongshou's paintings from the aspects of similar function, indicative function and stipulation function, in order to help us understand Chen Hongshou's painting language from a new perspective and better interpret the schema connotation of Chinese painting represented by Chen Hongshou.

Wide Sargasso Sea is the last work of Jean Rhys who is a British Caribbean female writer. It truly describes miserable fates of Creole women as "the other" under the double oppression of colonialism and patriarchy. Through analyzing fates of the heroine′s mother, her aunt and herself, the paper reveals tragic fates of Creole women in the context of white male culture.

In this study, acicular goethite FeOOH was prepared via a surfactant-assisted hydrothermal method,and the phase composition and morphology of the FeOOH specimens were studied by means of XRD, SEM and TEM. The effects of hydrothermal temperature, hydrothermal time and different surfactants on the structure and the purity of FeOOH specimens were investigated systematically. It was found that only the Fe2O3 phase but no FeOOH phase can be found in the specimen if not using the addition of any surfactant. The best experimental conditions for the high-purity, high-crystallization and uniform -FeOOH are that the CTAB   cetyltrimethylammonium bromide of 0.2 g or 0.3 g was used as the surfactant, and the temperature conditions were at 180 reaction 2 h.

Bletilla striata polysaccharide has many applications and development prospects in medicine and food science. In this experiment, the polysaccharides from Bletilla striata were extracted by ultrasonic-assisted extraction method. The single factor experiment and orthogonal experiment were used to find the best conditions and then identified its structure. The traditional water extraction method and ultrasonic extraction method were used to compare antioxidant activity of Bletilla striata polysaccharide. According to the data, the optimal extraction process conditions were obtained: the ultrasonic power was 400 W, the ratio of material to liquid was 1:35 g/mL, and the ultrasonic time was 50 min. The yield of the polysaccharide was 8.18% + 0.04% under this condition. The scavenging rate of DPPH?and?OH of Bletilla striata polysaccharide by ultrasonic-assisted extraction method was higher than
by traditional water extraction method. The polysaccharides obtained by the two extraction methods showed no significant difference in ABTS+?clearance rate, and none of them had O2-?clearing ability.

After experiencing the "memories of youth" in the early military life, the "diaspora context" of studying abroad and immigration, and then "world of mortals" in looking back at the old country, Yan Geling's novel creations have formed their own style. In these novels full of women's experience, Yan Geling has always hidden the conscious or unconscious incorporation and absorption of the trend of thought of the times. The evolution of women's images through historical periods shows the gradual development of women's "spiritual subject construction" and it reveals the writer's intention to seek female self-salvation.

The acceptability test finds that the wide scope interpretation of mou (which means some)is prominent in the co-occurrence sentence of mei (which means every) and mou; the narrow scope interpretation of yi (which means one) is prominent in the co-occurrence sentence of mei and yi, and the scope interpretation of the sentence of mei and yi is more partial. Semantic content and sentence pattern both have priming effects on the scope of the Chinese co-occurrence sentence of universal quantifiers and existential quantifiers, and the priming effect appears to inhibit the opposite interpretation. The comprehension mechanism of co-occurrence sentences of mei and yi reflects the relevant interpretation mechanism of Chinese quantifiers.

Article 234 of contract law provides for the continued performance of the original lease agreement after the death of the lessee. However, no matter in the accuracy of the legal text or the flexibility of the practical operation, Article 234 is incomplete. Therefore, by combing the disputes involved in the provision, this paper explains and responds to the related issues, and on the basis of defining the connotation and extension, puts forward the solutions of the protection of the interests of all parties with the goal of "having shelter", in order to contribute to the understanding and application of this provision, with a view to achieving "living in peace".

In international business activities like capital venture, public offerings, transnational M&A, financing, real estate transactions, the lexical deficiency often appears in the translation of business English documents. Based on the functional equivalence theory, the translation circle at home and abroad has rendered this phenomenon fundamental research. Taking the business document on the website of U.S. Securities and Exchange Commission as the main example, which contains compound words with bring-down, we find understandi ng and translating accurately the compound words can help deduce the corresponding Chinese words for bring-down. Throug h practical analysis, literal translation cannot resolve the lexical deficiency effectively, whereas transliteration, free translation and substitution can help readers comprehensively understand the meanings of the compound words. Based on translation practice, the amplification with business background can best solve the problem of lexical deficiency.

Through questionnaire, interview and other means, this paper finds out the main problems and potential of Hefei tourism service experience. According to the different types of scenic spots, combined with the tourism experience, the service experience upgrading strategy is proposed from the perspectives of constructing a promoted service system, combining with technology upgrading experience and linking with publicizing scenic culture.

As a special cultural phenomenon, the choice of a theme for custom painting mainly comes from daily life, which is full of humanism and a direct reflection of society. From the perspective of art, custom painting reflects the aesthetic fashion of different classes in society. This paper attempts to combine the golden periods of the development of custom painting in the history of Chinese and Western art: China's Song Dynasty and the Netherlands in the 17th Century. From the perspective of art sociology, it tries to see how Chinese and Western custom paintings constructed aesthetic values and dealt with the interaction between the function of custom painting and the motivation of creation, in order to form a new understanding of custom painting.

Abstract: The Doctrine of the Mean is an important component of Confucianism, a doctrine of thought founded by Confucius. On the one hand, this thought has been inherited and spread, profoundly affecting the Chinese people;on the other hand, it is often misunderstood and even criticized. A close reading of the Analects of Confucius reveals that the Doctrine of "the Mean" is actually the unity of three connotations: doctrine of harmony, doctrine of viability and doctrine of contingency.

With the deepening of housing market reform, the influence of individual factors on living conditions begins to weaken. Based on the CFPS data from 2010 to 2018, this paper makes an empirical analysis on the evolution of China's family housing area inequality from three characteristics: family, head of household and region. It is found that the family size has the highest impact on the housing area inequality, which is gradually accelerated with the reform of the market-oriented process. The social concept of buying a house before marriage and family group housing demand become the main factors to promote the inequality. Moreover, due to the policy influence in the process of market-oriented reform, the influence of the characteristics of individual family and head of household on inequality is gradually reduced, but they are still important factors. With the acceleration of urbanization and the deepening of market-oriented reform, the impact of urban and rural and regional factors on inequality is gradually weakening.

To cultivate comprehensively developed socialist builders and successors, colleges are bound to focus on aesthetic education. In view of the current instrumentalized and marginalized status of college aesthetic education and its challenging educating validity, it is necessary to return to the development of aesthetic education itself. Under the guideline of "psycho-action" construction, colleges are subjected to deepen curriculum reform and improve teaching art to improve the cognition of beauty; optimize the top-level design and enhance the connotation of activities to enrich the emotion of beauty; stabilize the network control and purify the network ecology to strengthen the will of beauty; expand the practice platform and strengthen practical guidance to innovate the behavior of beauty. Only in this way can various education systems be actively integrated into aesthetic education, which will shed light on the construction of "comprehensive aesthetic education".

Novecento is one of the masterpieces of the Italian writer Alexandro Barrico. The protagonist Novecento's rejection of disembarkation has aroused wide discussion. Many researchers have paid attention to the passive side of Novecento's behavior, which led the researches to slide into childhood determinism. This paper intends to explore the relationship between heterotopia and authoritative space in this play, and attempts to explain that Novecento's rejection of disembarkation is motivated by the power of heterotopia. When authoritative space attempts to invade and control the Other in heterotopia, the Other also endeavored to resist it.

During the epidemic prevention and control period, in order to implement the Ministry of Education’s requirements to suspend classes, but not suspend learning and teaching, colleges and universities in various places have made full use of the advantages and functions of "Internet plus education" to complete large-scale online course construction, teaching organization and supervision management in a very short time. In view of this, this paper obtains the mobile teaching platform data of special University for nearly 40 days, completes the cleaning,extraction, classification and summary operations, and objectively analyzes the online teaching situation of the University during the epidemic period. Based on the characteristics of data, this paper puts forward four teaching behaviors of online teaching, and formulates the supervision standard of "eight observation points" around the four teaching behaviors of online teaching, so as to provide reference for the evaluation of online teaching behaviors of similar colleges and universities, as well as for the supervision of online teaching in colleges and universities.

Anode materials in many commercial lithium-ion batteries are composed of graphite. In fact, theoretical capacities of SnO2 are far greater than that of graphite. But it also results in a large initial irreversible capacity and a poor capacity retention due to the volume expansion/contraction of Sn during alloying/dealloying reactions with Li+. MWCNTs not only have a higher capacity than graphite, but also they can be used as a support matrix forming novel metal/MWCNT composites which can take advantage of the higher capacity of metals and prevent the problem of pulverization too. In this work, SnO2 /MWCNTs nanocomposites were fabricated by chemical deposition method.SnO2 nanoparticles can be deposited on the outside and inner surfaces of the MWCNTs. It was proved that the content and inner diameter of MWCNTs in the nanocomposite electrodes indeed played a dominant role in improving the reversible capacity and cycling stability of lithium-ion batteries.

The university student union is the main student organization under the leadership of the Party and the guidance of the League, in which the majority of students carry out self-education, self-management, self-service, self-supervision. It is also the bridge between the school management and students. Through the analysis of the micro cases of the student union in the new era, such as "not-in-my-back-yard attitude", "small group", "second transmitter (who doesn't do the real work)" and "show affection in public", this paper makes clear the significance of the reform of the student union of colleges and universities, puts forward the reform thinking of strengthening the value guidance, improving the organizational support and deepening the work style building, so as to further strengthen the foundation for improving the organizational reform and innovation of the student union of colleges and universities.

At present, the key to expanding domestic demand is to release the consumption potential of rural residents. Infrastructure is the cornerstone and support of the implementation of the rural revitalization strategy. In this context, examining the role of transportation infrastructure in boosting rural residents' consumption is of practical significance. Based on the panel data of 16 prefecture-level cities in Anhui Province from 2003 to 2018, this paper empirically studies the relationship between transportation infrastructure and per capita consumption expenditure of rural residents. The results show that the acceleration of the transportation infrastructure process can significantly increase the consumption expenditure of rural residents. In the short term, this driving effect is more prominent, and the long-term effect depends on the follow-up of supporting facilities; sub-regional research shows that the impact of transportation infrastructure on rural residents' consumption in backward areas is more obvious. Therefore, further improving the rural transportation infrastructure and breaking the bottlenecks that restrict the sustainable development of rural areas should become the proper meaning of implementing the rural revitalization strategy.

The Great Learning is rich in the thought of inner-wisdom and outer-practice, which mainly emphasizes the learning of inner-wisdom to achieve self-reliance, and the learning of outer-practice to be helpful for others, and develops as a systematic way of self-cultivation, family regulation and state rule. Combining with the characteristics of the times and the needs of social development, we apply the basic principles of Marxism to the modern transformation of the thought of inner-wisdom and outer-practice in The Great Learning, and endue it with new connotations and forms of expression and give it new vitality. On this basis, we have taken the initiative to draw on some of the beneficial thoughts that play an enlightening role in fostering virtue through education in the new era, such as cultivating one's moral character, self-reliance and helpfulness, and the unity of knowledge and action, and make the good traditional culture of China become the spirit of the new era.

To improve the safety management capabilities of laboratory in colleges, based on the research about laboratory safety in colleges, the main sources of risk in university laboratories were analyzed under the background of new engineering. The principles of risk control were summarized, and countermeasures were proposed. Results show that both new engineering and laboratory safety in colleges have become research focuses nowadays. The experimental technology and personnel awareness were the main source of the other risks. The increase of environmental risk factors in the laboratories always result in the increase of risk. Commonly, the risk awareness would gradually weaken over time. There are many tools for laboratory risk identification, assessment and control. we
should select appropriate tools for different laboratory risk situations. So, the colleges should keep up with the times choose suitable measures and collaborate with each other to manage laboratory risk.
