Dude, I'm a choreographer. Let me give you some advice. You can see five translations of Ying Ruocheng (he plays Liu in the drama Teahouse). If possible, you can look at 1980 to 2000' s China Drama Yearbook (available in general libraries). Others should try to watch some famous plays. For example, selected plays of ancient Greece (one work for each writer), Shakespeare's Four Tragedies (read at least two), Ibsen's plays or selected plays of Ibsen (read A Doll's House, Ghosts, Public Enemies and Architects), and Chekhov's plays (read cherry orchard). Mozart's death), O 'Neill's collection of works (reading "The Iceman Comes, Walking by Night during the Long Day") and Selected Foreign Plays (1-6).
