Why does Bing Xin's grandson want to engrave "It is a waste of people's appearance to teach a child badly" on her tombstone?

Because in his later years, Bing Xin's son not only cheated on his marriage, but also treated his wife badly in the division of property. Bing Xin's grandson took his father to court but lost, so he wrote these eight words on grandma Bing Xin's tombstone on impulse. At that time, Bing Xin's grandson was completely impulsive, hoping to force his father to compromise with this extreme behavior. However, in the end, he not only failed to solve the problem, but also got himself into a lawsuit. Bing Xin and her husband have three children in their lives, and the only son is Wu Ping. Judging from the name Bing Xin gave her son, she actually wanted him to live a quiet and ordinary life. However, her son Wu Ping did lead a quiet life, but he did something unusual in his later years. Wu Ping and his wife have experienced ups and downs for many years, but in their later years, they wanted to end the marriage because of Wu Ping's infidelity. At that time, Wu Ping's wife was seriously ill. However, despite her illness, Wu Ping still wants a divorce and wants to pursue her love life in her later years. In fact, everyone thinks this is ridiculous. After all, Wu Ping is old, and I don't know how many days are left, but it really shouldn't be so quiet. Wu Ping insisted on getting a divorce. Therefore, Wu Ping's wife and Wu Ping negotiated for several years without results and had to divorce. After the divorce, Wu Ping and his wife's property was divided unfairly. As a cheating party, it is obviously unfair for Wu Ping to get so much property.

Later, Wu Ping's son, Bing Xin's grandson, took Wu Ping to court and lost the case. After the failure of the lawsuit, on impulse, he chose to run to grandma's tombstone and carve words on it? If you can't teach your son well, you will be a fool. Eight words, and left a letter accusing his father there. His purpose is actually to put pressure on his father and take his anger out on himself and his mother, but such a move is really radical.
