The report of the 20th National Congress of the Communist Party of China (CPC) put forward the idea of "promoting cultural self-confidence and self-improvement, and creating a new brilliance of socialist culture", which has aroused a warm response in the literary and art circles. As an important part of socialist culture, the online audio-visual industry plays an important role in "launching more excellent works to enhance the people's spiritual strength", "meeting the people's growing spiritual and cultural needs", and "enhancing the influence of the spread of Chinese civilization". The consistent action guide of Tencent Video is to continuously output high-quality content and tell good Chinese stories. Over the years, in the work of content layout, production, scheduling, operation and other aspects, we have deeply realized that the network audio-visual platform should do a better job of "three grasp". Grasp the pulse of the times and find the correct position of the times. "Portraits for the times, biographies for the times, and moral values for the times" is not only a requirement for writers and artists, but also a response to the needs of the audience for high-quality products of the times. In recent years, we have produced and broadcast a number of works with realistic themes, such as "Ahebola Front", "Sweeping the Dark Storm", "Mountains and Seas", and "On the Field of Hope". Focusing on major events such as aiding Africa to fight the epidemic, eliminating the black and evil, overcoming poverty, and revitalizing the countryside, we have closely followed the main theme, described the hot social life with rich images and vivid picture language, and demonstrated the spiritual outlook of the Chinese people in the new era.

The online audio-visual platform has great potential in developing advanced socialist culture, carrying forward revolutionary culture, and inheriting excellent traditional Chinese culture.
