Compare the willow tree to a young woman's ancient poem.

Waist as thin as a willow, Pan Fei as beautiful as a lotus. By the way, Xiaoman is a person's name, Bai Juyi's maid. It is said that the countryside is beautiful (the poet is so blessed). I guess many people think "Xiaoman" is an adjective. . . . I don't remember whose concubine Pan Fei was, but that's where the word "light-footed" came from. Hope to adopt.
