When I was a child, I didn't know the moon, so I called it a white jade plate, which means

White jade plate refers to the moon. When I was a child, I didn't know the moon, so I called it a white jade plate, which came from Li Bai's "Journey on the Gulang Moon", meaning that I didn't know the bright moon in the sky when I was a child, so I called it a white jade plate. Li Bai compared the moon to a white jade plate by metaphor. The poem "Gulangyue" is an excerpt from "I don't know the moon for an hour" and is called "White Jade Plate". I also doubt the Yaotai Classic, which flew at the end of Qingyun Mountain. The author Li Bai, whose word is Taibai, is a famous violet layman, also known as "fallen fairy", a great romantic poet in the Tang Dynasty, who was praised as "poetic fairy" by later generations and called "Du Li" with Du Fu. In order to distinguish Li Shangyin and Du Mu from the other two poets, namely "Little Du Li", Du Fu and Li Bai are also called "Big Du Li".
