Why did Lao Dan become a tree?

Lao Dan didn't become a tree. Lao Dan, one of the traditional operas in China, refers to playing the role of an elderly woman in the drama. Dialects in China have different names, but their expression features are basically the same. In performance, female Lao Dan's requirements are different from those of male Lao Dan. It is often more difficult for female Lao Dan than male Lao Dan in singing, sound processing and singing beautification. Lao Dan's performance is more important than singing, and he also created an amiable old woman. In China's Peking Opera, you usually don't play the leading role, but you play the leading role from time to time, such as Kang in Jin Fenghua, Wu in Chisang Town, and Join the Dragon Robe in Visit the Queen.

Therefore, Lao Dan has not become a tree.
