What is the reason for Xiao to leave his daughter and children in Brilliant Star Man? Why is Cheng Shaoshang pathetic?

Yuan Yi Jr. left Cheng Shaoshang in The Splendid Star Han because she thought that even if her daughter was badly taught in the future, Cheng Jia would not suffer. It also shows from the side how deep-rooted the idea of son preference was in those days, so Yuan Yi Jr. made such a decision and left the young Cheng Shaoshang. Details are as follows:

First, Yuan Yi left her daughter Cheng Shaoshang because she felt that even if her daughter didn't teach well, it wouldn't hurt her family, but her son was different and needed to be taught well.

In fact, the reason why Yuan Yi left his daughter Cheng Shaoshang has already been said in the play. She said that a son is a symbol and can represent a family. If her son is not taught well, then her words and deeds will affect the whole family and even bring misfortune to the family. The possibility of genocide is quite high, but there are very few cases of genocide caused by her daughter's poor teaching throughout the ages. After seeing the old lady and the Cheng family at home, Xiao decided to leave her daughter, thinking that she would forget it in the future.

Second, Cheng Shaoshang's tragedy should be that no one has ever cared about her, and even her own mother is indifferent to her.

I think the tragedy of Cheng Shaoshang is that any decision made by Yuan Yi Jr. is rational, and she doesn't care about her daughter's feelings at all. Whether staying at home or coming back after many years, her attitude towards Cheng Shaoshang is completely centered on Xiao Yuan Yi, and then Cheng Shaoshang passively chooses to accept it. As long as Cheng Shao doesn't accept her, she will get angry and scold her. This kind of complete interest relationship, without mutual affection between mother and daughter, really makes people feel that Cheng Shaoshang is very poor, and

Finally:

Fortunately, Cheng Shaoshang met Ling Yi. Fortunately, Ling Yi gave Cheng Shaoshang all her tenderness, otherwise her life would be really too bitter.
