Look at Xi Murong's Xiao Jing and ask a question.

The theme image of this poem originated from Untitled, which was long before I met her, but it was longer than Li Shangyin's After Breaking Up: looking in the mirror in the morning, she saw that her hair cloud was changing, but she bravely faced the cold of moonlight with her evening song.

The author painted "Xiao Jing" and visualized it, which is a metaphor for beautiful youth. Write "hide" first, then think it is "secret", and finally write "can't hide" Tortuous, euphemistic, implicit wrote the sigh that time flies and youth is no longer there, full of sense of time and vicissitudes.
