It takes ten years to grow trees and a hundred years to cultivate people" is Guan Zhong's famous saying, which comes from "Guan Zi Quan Xiu": "A one-year plan is better than a tree valley; a ten-year plan is better than trees; a lifelong plan is better than trees. Nothing better than tree people. A tree that harvests one harvest is a grain; a tree that harvests ten harvests is a tree; a tree that harvests a hundred harvests is a human being. "The meaning of this passage is that for the country, the most profitable thing is to cultivate talents. Once talents are successfully cultivated, they will "get a hundred harvests from one tree." This is the lifelong plan of the country to govern the country. Then people will always control the people. This passage is summarized as "it takes ten years to cultivate trees and a hundred years to cultivate people", which is a metaphor for "the great significance of cultivating talents, and it also means that cultivating talents is not easy."
