Children should be biological, and wealth should be self-respecting.

The children must be born, and the wealth must be earned by oneself. It is a folk proverb, which means that only a son can be loved if he has given birth to one, and only a son can be cherished if he has earned it himself. In fact, this statement is somewhat outdated. It does not mean that you should not kiss the child if you have not raised it by yourself. This goes against Mozi's idea of ??"universal love". As the old saying goes: Old people are like the old people, young people are like the young people.
