There is a poem in the textbooks of several grades, which is called "I will walk until the water blocks my way, and then sit down and watch the rising clouds".

My retreat in Zhongnanshan

Wang Wei

My middle-aged heart found its way, and I came to live at the foot of this mountain.

Come and go alone, in beauty, that is everything to me.

I will walk until the river blocks my way, then sit down and look at the rising clouds.

One day I met an old woodcutter, laughing and laughing, and never came back.
