A scholar dies for a bosom friend, and gives way, one of The Four Assassins in the Spring and Autumn Period, speaks. Yurang was the retainer of the branch family in the Spring and Autumn Period. In 453 BC, Zhao of the State of Jin defeated Zhi in Jinyang with Han and Wei. The head of the Zhi family was killed and the head was used as a wine vessel. In order to repay the kindness of meeting him directly, Yu rang went to the toilet many times and swallowed charcoal to assassinate him. Finally, he committed suicide and died, leaving behind the eternal swan song of "a scholar dies for a confidant, and a woman looks after herself."

A scholar who dies as a confidant means that he is willing to give his life to those who appreciate and cultivate himself.

Yu rang, the grandson of Jin Biyang, started as an expert in Fan Zhong and said nothing. When he went, he knew Bo and Bo's pet. However, Sanjin, who knows his surname, is most resentful of knowing Bo, so he regards his head as a drinking vessel. Yu rang fled to the mountain and said, "Wow! A scholar dies as a bosom friend, and a woman is her lover. I know my family's grievances (through "hatred"). " He changed his name, became a prisoner, went into the palace to dirty the toilet and tried to assassinate Xiangzi. Xiangzi went to the toilet, moved his heart, asked about the smear, and then Yu shouted. Blade said: "I want to avenge Zhi Bo!" " I want to kill it. Zhao Xiangzi said, "He is an honest man, and I want to avoid him. And I know that Bo is dead and childless, and I want revenge. This world is also a sage. " Release it.
