Han Yuefu's ancient poem "Long Songs": "Sunflowers in the youth garden are basking in the sun. Spring fills the earth with hope, and everything presents a scene of prosperity. I am always afraid that when the cold autumn comes, the trees in Ye Er will turn yellow and the grass will wither. All rivers return to the East China Sea, when will they return to the West? If you don't work hard, the boss will be sad. "
Cao Zhi was forced to write a seven-step poem.
Boil beans and burn beans, and simmer black beans. Honey burns under the pot, and beans cry in the pot. We were born from the same root, so why should we speculate with each other!
