On September 19th, Lu You had three persimmons with red leaves, and a closed-door scholar laughed.

Lu You, a poet in the Southern Song Dynasty, is the author of Xueshu.

The whole poem is as follows:

On September 19, persimmon leaves were red, and the closed-door scholar laughed at Weng. Who in the world promises to make money directly? The bottom of the window has been used for ten years.

Old vines are full of frost and snow, and thin dumplings are empty in the sea. That is, today's comments on He Zudao are ridiculous, and self-confession after 500 years.
