1, Tsing Yi is also called Zheng Dan. The name of Tsing Yi comes from the fact that most of the characters are dressed in blue, mainly singing. The characters range in age from youth to middle age. If it is an old role, it will be played by Lao Dan. The characters in Tsing Yi don't move much, and they are mainly steady. The classic plays of Tsing Yi include Xue Mei's godson, Drunk Imperial Lady, Farewell My Concubine and so on. Mei Lanfang, a master of modern Peking Opera, is good at Tsing Yi.

2. Hua Dan is a branch of the "Dan" corner of Peking Opera. Hua Dan once originated from a sentence in Xia Tingzhi's ancient book "Collection of Brothels" in Yuan Dynasty: Hua Dan was a man who broke his face with ink, but paid more attention to singing and doing things. Unlike Tsing Yi, who plays a solemn woman, and Lao Dan, who plays an elderly woman, Hua Dan plays more lively and lovely women with romantic thoughts, and also plays more provocative and behavioral roles.
