The story of a tough person.

A young man among the butchers in Huaiyin insulted Han Xin and said, "Although you are tall and like to carry a knife and a gun, you are actually a coward." He insulted him in public and said, "if you are not afraid of death, stab me with your sword;" If you are afraid of death, climb under my crotch. " So Han Xin looked at him carefully, bent down, prone on the ground, and climbed down from his legs. People all over the street laughed at Han Xin and thought he was timid.

Later, Han Xin became a general. Although insulted by this person, Han Xin didn't retaliate.
