Guanzi Quanxiu takes ten years to cultivate trees, but it takes a hundred years to cultivate people.
Guanzi's sea is full of water, so it can become a big one. The mountain does not care about earth and stone, so it can be high; A wise master never tires of others, so he can become a crowd.
A gentleman in charge of a pipe makes things, not things.
It's easy to make a pipe first, and then it's difficult.
A year's work in charge of a pipe is like a tree valley. Ten years' plan is nothing more than trees; A lifelong plan is nothing like cultivating people.
