How is a bad guy made?

Xie Wendong squinted and saw six men sitting at a round table on his right hand. The light in the ballroom was dim. He could not see the faces of several people clearly. The accent seemed to come from the south. Turned his head and looked down at his feet, it was a girl less than twenty, dressed like a waiter, with loose hair, sitting on the ground, covering her face with one hand, unable to get up for a long time. This kind of thing happens almost every day in dance halls, nightclubs and other entertainment places. Xie Wendong did not want to meddle in other people's affairs, but just as he was about to dodge, one of them seemed to be still dissatisfied, pounding the table and shouting loudly, chattering and full of foreign languages. Perhaps foreigners have a natural sense of superiority in China, perhaps people's unspeakable fear and admiration of foreigners cultivate their arrogance, and finally the man rushed to the waiter and slapped him in public. His companions did not mean to stop him at all, and they all laughed while drinking and watching the fun. Xie Wendong lifted his foot and shrank back. He turned his head and asked Gao Qiang, "Qiangzi, haven't you fought with your fists for years?" Gao Qiang thought hard and said, "About two or three years." "Yes!" Xie Wendong nodded and said with a smile, "I have a chance to practice my technique today." Before he had finished speaking, he suddenly stepped in and grabbed the man's wrist. "You've had enough," he said with a smile. The man was in high spirits when he was suddenly caught. He turned around and saw a young man in his early twenties. He was not tall and slightly thin. His eyes were curved into two crescents. He was looking at himself with a smile. He did not put the student-like Xie Wendong in the eye, snorted, and threw his arm hard, but the other side's palm was like a pair of pliers, fishing clasped his wrist, did not move a cent, but made him shiver with pain, he shouted a few words. His companions got up one after another and leaned over to Xie Wendong. A young man of medium height with high cheekbones shouted, "Let go of your hand. Do you know who this is?" Gao Qiang stepped forward,316ti stainless steel
