She had to obey her family's arrangement because of her poor fortune. The person she married was Wu Pin, but to put it mildly, she was married. To put it mildly, she was actually sent to the wedding, because Wu Pin was seriously ill at that time and would not live long. His family wanted to find someone to celebrate and finally chose Zhou Ying.
Some people say that she didn't go to Wu Jiazu's grave because she had no children, which was a very serious thing in ancient times. Originally, she had a daughter, but unfortunately she died at an early age. Later, she also had no children. Although she adopted the children of the Wu family, she is not her own. This family is very prominent. This man's thought is still very feudal. Even if Zhou Ying let them live the life of the richest man, she may still look down on her from the bottom of her heart. Anyone who has seen that TV series must know that Zhou Ying's role in those people's eyes should be to make money, and she is in the TV series.
But the most likely reason should be that she was afraid that the descendants of the Wu family would be thin, so she chose not to enter the Wu family grave. And this seems to be confirmed by her descendants. I have to say that this woman's courage is candidly admit defeat by some men, and her life is really full of legends.
