Even if a person's relatives don't care about themselves and are not enthusiastic, a person's children are the closest people and will not be closer to them because of what they get. Although six relatives are not close, children are not. This is a famous saying of Mencius. This sentence conveys a family concept that blood is thicker than water, that is, there should be an emotional connection of mutual support and care between relatives, encouraging people to attach importance to family ties, and reminding us to cherish, cultivate and maintain good family ties when getting along with relatives.
