In the early 1940 s, beginning with the performance of the famous play Sunrise by Cao Yu,an upsurge of "full-scale drama" had arisen in Yan’an. On the surface, putting Sunrise on stage aimed at implementing the "united front" strategy. But the deep reason was that considering the rush and carelessness in the preceding performances of the theatrical movement, Lu Xun Art Academy and other professional groups tried to improve theatre by performing classic plays. Incorporating various aspects,including director, actor and stage, the performance was a great success. Thereupon, a lot of Chinese and foreign plays were performed in Yan’an. However, in the context of the Anti-Japanese War, the performance of classic plays failed to bridge the huge gap between theatre and reality, and was therefore caught in a dilemma. With some additional crises, such as the Southern Anhui Incident, such theatrical practice was finally interrupted.
