A dead tree grows again when spring comes, and no one can grow young again twice.

Explanation: Withered trees can sprout again in spring, but there will not be two youth years in life.

This poem is excerpted from "Zengguang Xianwen". "Zengguang Xianwen", also known as "Xianwen of the Past" and "Xianwen of Ancient and Modern Times", is a children's enlightenment book compiled during the Ming Dynasty in China. The title of the book was first seen in the opera "The Peony Pavilion" during the Wanli period of the Ming Dynasty. From this, it can be inferred that the book was written during the Wanli period at the latest.

"Withered trees will sprout again in spring, and no one will be young again twice" means: withered trees will sprout again in the next spring. But you only live once, and if your youth is wasted, you can never make up for it. From the Encouragement to Study chapter of "Zengguang Xianwen", a children's enlightenment book of the Ming Dynasty.

Full text of the source of the poem:

A dead tree grows again in spring, and no one can grow young again twice.

Don’t worry about growing old and not succeeding, just worry about being young and not learning.

The waves behind the Yangtze River push the waves ahead, and the people of today are better than the people of the past.

If you spend your years in vain, you will regret it when you are old.

If you have ambitions, you will not grow taller in years; if you have no ambitions, you will live a hundred years in vain.

If a young man does not work hard, the old man will be miserable.
