Who are the characters in Xian Sao and what kind of people are they?

Xiaogu Opera is a very popular traditional drama in the north, and many dramas, such as Pingju Opera, Quju Opera, Lu Opera and Qiang Mao, come from it. The source is unknown, and there are also sayings such as Wang Dengyun Divorces His Wife, Love a Daughter without Paying Attention to His Daughter-in-law, and A Door with Three Sages. Plot: the son of Yao followed Meng to marry into gold, and the husband and wife loved each other. Yao is partial to his daughter and often uses the abuse of his daughter-in-law as an excuse. Ying Ying felt wronged, cleverly protected her sister-in-law, and took herself as an example to persuade her mother. The Yao family changed, and the family was harmonious from then on.

There are four main characters in the play:

Mother-in-law-Yao (Yao in Pingju, Diao in Luju and Quju)

Daughter-in-law-Jin family (Li or Li Ronghua in Lu Opera)

Daughter (called Sister-in-law by Lu and Wang Guini by Qu)

Son-Zhou (in Lu Opera)
