Poetry is a poet's way of killing time. Here I want to talk about Li Qingzhao again. She is a bad girl, and there is really nothing to look forward to except writing poems.
For Du Fu, poetry can be used to entertain guests. That ya didn't have the money to treat, so she made three dishes and one soup with a handful of leeks, two eggs and a piece of tofu, accompanied by a poem "Jueju", two orioles singing green willows (two fried leeks with egg yolks) and a row of egrets flying to the sky (a string of fried leeks with protein). The window contains autumn snow in Xiling (boiled tofu), and the Wu Dong Wan Li boat is moored at the door (two eggshells float in the soup made of water). Really save money.
In contrast, Li Bai is the most unruly. That ya almost used poetry to repay the person who gave him a drink. If it weren't for Wang Lun, who would remember that a man named Wang Lun sent Li Bai wine? A song "Into the Wine" has a great momentum at the beginning, but it shows its true colors at the end. "Spend a lot of money, give it to the boy, get good wine, and share joys and sorrows with you." This is to urge the owner to sell horses, clothes and wine for him. What a wonderful life this is.
