Meaning of the Idiom
ou xin li xue（to vomit one’s heart and shed one’s blood）
Li He was a famous poet in the Tang Dynasty.
It is said that Li He did not set up a topic first when composing poems, but paid attention to discovering materials in life. Every time he goes out, he always rides a skinny horse, takes a little boy with him, and carries a kit on his back. He thinks while walking, and when he recites a good sentence, he writes a scroll on the horse and puts it in the kit.
His mother waited for him to go home, checked all his pockets and found that he had written a lot, and often complained to him pitifully: “Don’t tell me you have to vomit all your hard work before you give up!”
Li He wrote poems too hard, which damaged his health. He died at the age of 27, but he left many poems with unique artistic style for later generations, which added splendor to the Chinese poetry world.
