When Li Bai bowed his head, he thought of the poem "Thinking about a Quiet Night".

The moonlight is bright in front of the bed.

Like frost on the ground.

Looking up at the bright moon in the sky,

Bow your head and miss your hometown.

Li Bai looked down and thought of his father, brothers, relatives and friends in his hometown, and the mountains and trees in his hometown.

The action of "bowing your head" depicts the poet completely lost in thought. The word "miss" left a rich imagination space for readers: the old brothers, relatives and friends in that hometown, the mountains and rivers, the grass and trees in that hometown, the lost years and the lost past are all thoughts. A word "Xiang" contains too much content. Silent Night Thinking is a five-line poem written by Li Bai, a poet in the Tang Dynasty. This poem describes the poet's feeling of looking up at the moon in the house on an autumn night. Metaphor and contrast are used in the poem to express homesickness. The language is fresh and simple, and the charm is endless, which has always been widely read.
