Why did Sun Shaoping choose a widow with a child to live with him in Ordinary World?

Few people can understand Sun Shaoping's spiritual world. The general text explanation is too pale. Let's just say that in today's society, many people sharpen their heads, fight and grab things that may not belong to them. However, Sun Shaoping may not accept what many people get before him. First of all, he is a man who thinks of others in everything. In the underground, he can lay down his life to save the workers, but what else can he not give up? Secondly, what he really wants to accept must be justified. He doesn't want the best thing. Third, he and Huiying established a real relationship in that special environment. The monitor Wang gave his life to save the workers underground. His family are all people who like to help others. And Xiao Xia is a kind of person in his bones, so after Xiao Xia left, Huiying was the first choice. More importantly, Huiying stuck to the life in Shao Ping, chose to be with Huiying, and realized Shao Ping's wish, that is, to help the monitor take care of their orphans and widows. What the world sees is only the social status difference between Xiao Xia and Shao Ping Huiying, but they don't see that these three people have a highly similar inner world.
