What are the ancient poems that describe children growing up in an instant?

Extended information:

Worry about everything?

don? Du fu

recalled that he was still a child at the age of fifteen and was as healthy as a yellow calf.

pears and jujubes are ripe in August before the court, and trees can return a thousand times a day.

Now that it's 5, there are only a few rows to stand on.

a strong master laughs for his master, and a sad life is a collection of worries.

the entrance is still empty, and my old wife sees me in the same color.

The idiot doesn't know the father-son ceremony, and he is called Angry Asking for a meal to greet the East.

The first sentence doesn't talk about worry, but about happiness; Don't say old, but remember less. A fragment of his teenage life can be seen from the poem at the same time. When the poet recalled his youth, he was carefree, healthy and energetic, which was really full of vigor. The so-called "healthy as a calf" is a vivid portrayal. Yang Lun in Qing Dynasty called this sentence "to describe it absolutely, just to set off the following" (Volume 8 of Du Shi Jing Quan). In front of the court, pears and dates are ripe in August, and trees can be returned a thousand times a day. That is, when the pear and jujube are ripe, the young Du Fu frequently goes up the tree to pick them, a thousand times a day. The so-called "thousand times" is just an exaggerated tone, which means more.
