Why doesn't Lao Tzu give lectures and accept disciples everywhere like Confucius?

Confucius teaches gentlemen, and gentlemen are middle and senior managers. There are a large number of people, so they need to give lectures everywhere and collect disciples everywhere.

Laozi teaches saints, and saints are world leaders, which are hard to find in a hundred years.

Confucius loved the people, and when he saw that the avenue in the world was abolished, the ceremony collapsed and the music was bad. He wants to restore social order, devote himself to heaven and earth, serve the people all his life, know what he can't do, recruit apprentices widely, and carry out ritual and music education.

And I do nothing, make no mistakes, don't pray, abandon the hidden road when I see it, and society has its own way of development, so I will do what I have to do. So I don't accept apprentices, only apprentices ask the master.
