In the four years immediately following World War II, from 1945-1949, peace across the Taiwan Strait enabled many excellent plays, written by the most well known Chinese writers from 1930 to 1949, to be put on stage in Taiwan. These writers included Cho, Yu, Tian, Han, Chen, Bai-Cheng, Huang, Zuo-Ling, Wu, Zu-Guang, Ah-Ying, and Yu, Ling. Among these plays, Cho, Yu's plays were performed the most, and were also the most well known among Taiwan's theatre-goers. In addition, because Cho, Yu's pieces were regarded as the paradigm of Chinese theatre, they were actively promoted and performed again and again by both government and public entities. Some of Cho, Yu's plays were even adapted into Taiwanese-language plays, which gave a very positive stimulation to the development of Taiwanese-language theatre.Through the exploration of this topic, I hope to depict a clear picture of theatre history post-World War II, political and literature competition across the Strait, and the study extension of Cho, Yu's artworks.
