In Wang Wei's farewell, he expressed his thoughts for his relatives who did not return to his mother.

Wang Wei's poem "Farewell" expresses his thoughts about his relatives who have not returned to his mother. "But don't ask questions when you go.

White clouds pass through there without end. "

"But don't ask,

White clouds pass through there without end. The poet comforted his friends when he learned that they were "dissatisfied". He advised his friends to go to the mountains instead of worrying about the world's ups and downs. Only the white clouds in the mountains are boundless. What is said here is that there are endless white clouds in the mountains, and the "exhaustion" and impermanence of fame and fortune in the world are contained in them. These two sentences are very complicated, rich in meaning, and the charm of the poem is very strong. There are poets' sympathy, comfort and yearning for friends, their own resentment against reality, their denial of human glory, and their yearning for seclusion in the mountains. It seems to be broad-minded and detached, but it also has some helpless emotions.
