Li Ne married Xu Ning soon. After the marriage, Li Ne gave birth to a boy named Xu Xiaoning on 1972. The world of two people has become a family of three. It stands to reason that life should be happy, but marriage is not love. After bidding farewell to the romance of the affair, what we face every day is the triviality of daily necessities. At the same time, love alone in marriage is not enough. Both husband and wife's outlook on life, outlook on life and so on must be matched enough. Only in this way can we fight against all kinds of chaos after marriage. However, due to different backgrounds and educational levels, the marriage life of Li Ne and Xu Ning gradually became disharmonious. With the deepening of the contradiction, the gap between the two became wider and wider, and finally the marriage ended in divorce because it could not be reconciled. After the divorce, Li Ne returned to Beijing with his son Xu Xiaoning, because Xu Xiaoning was only a few months old at that time, so he had no impression of his father, but because of his mother's love, Xu Xiaoning's childhood was also extremely happy.
