According to legend, Su Dongpo once discussed poetry with his sister and poetry friend Huang and learned from each other. After my sister said "breeze and willow" and "plum blossom and light moon", I asked my brother to add a word to them and say something poetic. Su Dongpo immediately said: "Shake" in the front and reflect "in the back", that is, "the breeze shakes the willow and the bright moon reflects the plum blossom." Unexpectedly, Su Xiaomei called it "inferior". Su Dongpo thought about it carefully and said proudly, "Yes,' the breeze and the willows dance together, and the plum blossoms are hidden in the moonlight'. ""Little sister smiled and said, "Not bad, but still not up to grade." Huang Gu couldn't help asking, "What do you think?" Su Xiaomei read: "The breeze helps the willows, and the plum blossoms are defeated in the bright moon." Su Dongpo and Huang Gugu were chanting and pondering, and they couldn't help but say that it was wonderful.
