Classical Chinese: selling garlic sister-in-law

Yang Er, a native of Nanyang, is proficient in boxing. Every time he goes to the martial arts school to teach his apprentice the skill of gun and stick, there are many people watching. One day, an old man selling garlic was watching. He kept coughing and narrowed his eyes. In his words, he is very disdainful of Yang Er's boxing. Yang Er "xianggong" was very angry. He called the old man to his side and punched a pile of brick walls, which sank about a foot underground. Proud to say to the old man: "old man, can you be like me?" The old man said, "You can only hit the wall, not hit people." Yang Er Xianggong; "You old slave can let me fight. Don't blame me for killing you!" The old man smiled and said, "I'm dying." If I can win your reputation by dying. There is nothing to regret when you die. " The old man tied himself to a tree and unbuttoned his clothes to show his stomach. Therefore, Yang Er posed ten paces away, raised his fist and gave the old man a good beating. The old man was silent, only to see Yang Er, the "xianggong", kneeling on the ground and kowtowing to the old man, saying, "I know the crime of being born late." He tried to pull out his fist, but it was already in the old man's stomach and he couldn't pull it out. He begged for a long time, and the old man let go of his fist and jumped on a stone bridge. The old man picked up the garlic and walked slowly without telling anyone his name.
