Laozi said: Jianghai can be the king of all the valleys, and because of its goodness, it can be the king of all the valleys. It is a saint who wants to go to the people and must say it; If you want to be an ancestor, you must be behind you. It is based on saints, and the people are not heavy; Go ahead and the people will not be hurt. This is the music of the world, and I never tire of it. There is no dispute, so the world cannot compete with it.

It probably means that Jianghai can become the king of all waters because it is good at handling situations, so it can be called the king. Similarly, if a saint wants to stand on the commanding heights and lead the people, he must know how to be humble in words; If the holy king wants to stand in front and lead the people, he must put his own interests behind; Only in this way will everyone not feel burdened and hurt.

Then, people in the world will be happy to support him without feeling tired, because he does not compete with anyone, so no one in the world can compete with him, and the world belongs to him. This is what Laozi said: "The husband does not dispute, and the world cannot compete with him."
