Silent Night Thinking is a five-character ancient 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 his house on an autumn night. From "doubt" to "looking up" and from "looking up" to "bowing down", the whole poem vividly reveals the poet's inner activities and vividly outlines a vivid picture of homesickness on a moonlit night.
