Zhao is a shrewd man. Because he does have blood on his hands, and killing people is really disgusting, he is particularly filial, knows women well, and has a certain passion. Because he was rich and powerful, he married many concubines. Among his many wives, only Tie Lihua gave birth to a child. If the children are boys, then these babies may be the only heirs of the Wang family.
In the story, we can see that Zhao is a very overbearing person. Because of his power and wealth, he is an uncompromising man in his hometown. Even if such a person can understand and value a lady again, his function and overall strength will not allow him to maintain monogamy in the feudal society of China, and he is a man in a very feudal society, which is incompatible with the inner strength of Tie Lihua.
