All genres of traditional Chinese drama undergo changes to certain degrees. Emphases should be put on the preservation of individuality of each genre on the one hand, but on the other hand, inevitability of changes should also be recognized. We should not restrict subject matter of creation for maintenance of individuality of the genre. Rather, we should improve the artistic expressiveness of the genre through innovations. When a new variation emerges from the old genre of drama, we should acknowledge it, instead of discriminating against it for the purity of the genre. In accordance with the postmodern cultural view, boundaries between genres of drama can be broken and obscured, and attributes of genres evolve dynamically. On this issue, views from mainland China and Taiwan disagree. Nevertheless, contradictory views form tension, which is beneficial to the development of traditional Chinese drama.
