What are the poems that express the meaning of "leaving children with tears"?

Lipper

There is a blue mountain line north of the Great Wall.

To the east of the city is a white waterline.

Here you must leave me and drift away,

Like loose grass hundreds of miles away.

I will think of you in the clouds,

So think of me in the sunset.

We waved goodbye,

My horse brays again and again.

Green mountains cross the north of the outer city, and quiet white water flows around the east of the city. When we leave here, like a piece of loose grass dancing in the wind, Wan Li travels far. You are like a cloud in the sky, and I am reluctant to part with you like a sunset. We waved goodbye at once, but the horse didn't want to part, but couldn't help whistling. This poem is like an oil painting. The beauty of humanity and nature are intertwined and colorful.

A thousand miles away in Huang Yun,

The north wind blows geese and snow in groups.
