Under the background of "Going-out" strategy of Chinese culture, Lu Opera, as an important part of "Luzhou Culture", can’t truly go abroad without the research on its translation and introduction. Through field survey, it is found that the current translation and introduction of Lu Opera is faced with some problems, such as inadequate literature, insufficient translation practice, and limited promotion channels. On this basis, starting from the poly-system theory, the author suggests that in the translation and introduction of Lu Opera, we should choose the theme that fits the ideology and values of overseas audiences, adopt the translation and introduction strategy suitable for Lu Opera, and give full play to the promotion role of well-known publishers and new media, so as to promote the acceptance of Lu Opera overseas. It is concluded that the poly-system theory provides a feasible method for the translation and overseas promotion of Lu Opera.
