What does the poem "ten years to plant trees, a hundred years to educate people" mean?

Interpretation: Metaphorically speaking, cultivating talents is the long-term solution. It also means that it is not easy to train talents.

Ten years of trees, a hundred years of people? [Shinian Schm, Bignian Schlon]

From: "The Full Show of Pipe": A year's plan is like the valley of trees; The ten-year plan is nothing more than a tree; Lifelong planning is nothing more than cultivating people. A tree gets a tree, and the valley is also; Ten wins in one tree, and wood is also; There are many things in a tree, and so are people.

A year's plan is like all kinds of crops; Planning for ten years is like planting trees; Lifelong planning is like cultivating talents. Crops are harvested after one year of cultivation; It is a tree that can only be harvested after ten years of hard work; After a hundred years of hard work, what you gain is talent.

Example:

1, it takes ten years to grow trees, but it takes a hundred years to cultivate people. This sentence tells us that we must start from an early age to cultivate talents.

2. As the ancients all know, it takes ten years to grow trees and a hundred years to cultivate people. We should do a good job in talent training.
