Knock out teeth and swallow blood.

Bite your teeth and swallow your blood, you are wronged and don't want things to get worse. And punched a tooth and swallowed it. Allusion: According to legend, Dharma came to China by boat from India, landed in Guangzhou, and first went to Jinling (now Nanjing). After passing the place where Master Shen Guang gave lectures, he went in and asked Shen Guang, "What are you doing here? The divine light said, "I am preaching. Dharma asked again, "What is the lecture for?" Shen Guang said, "For life and death. The Dharma says, "The Dharma can't be said, nor can it be said. When you say black is words and white is paper, how can you live and die? Hearing this, the Shen Guang said angrily, "you mo Luo Cha! How dare you slander Buddha, law and monk! " Say that finish, with iron beads against the dharma patriarch's face! Dharma was knocked out of two front teeth without any defense. Father Dharma believes that if you spit your teeth on the ground, this place will suffer from drought for three years (because the saints' teeth fall on the ground, the sky will commit crimes, and people here will be punished for not raining). Dharma couldn't bear to let the people in this place suffer from drought, so he swallowed two teeth into his stomach. The so-called "knocking out front teeth and swallowing blood" left this allusion. Another way of saying it: Zeng Guokun, a famous ZTE star in the Qing Dynasty, was a real loser before defeating the Taiping Heavenly Kingdom, but he was never ashamed of his failure, let alone discouraged, but gained experience from it. His most famous words are: "Repeated defeats and repeated wars" and "Broken teeth and swallowed blood, broken hands and broken bones, and bravely marched forward".
