In fact, there are many such things in reality, and the dragon gives birth to nine children, each of which is different. Even if it is born to parents, there will be a big gap between personality and character.
Parents need children to take care of them when they are old. If they are unwilling to take care of the elderly or perfunctory at this time. Old people will see the true face of children, so they will leave all their property to filial piety. Therefore, I support this practice, which is unfilial to the elderly and has no right to their property.
