This is an abstract of my friend which is translated by me. Please help me correct it. Thank you! Xiang Peiliang has made a great achievement in both drama theory and drama composition. In the process of criticizing Guo Moruo’s early historical dramas, he launched explorations on the ontology of drama art consciously. In the area of modern Chinese drama, on the one hand, he has bulit one of the few drama theories based on the thoughts of ‘Emotional Behavior’. On the other hand, he has blended drama composition with his drama stand. Hence, from two dimensions of both theory and compositon, he has promoted the development of modern Chinese drama. Please help me. I really appreciate you!
