What poem is red wall fu?

Chibi Fu is of course Fu. Regarding the difference between poetry and Fu, Lu Ji, a writer in Jin Dynasty, once said in "Wen Fu" that poetry is beautiful because of emotion and delicate because of body. In other words, poetry is used to express subjective feelings and should be written beautifully and delicately; Fu is used to describe objective things, and it should be written clearly and smoothly.
