Che Yin, the word Wuzi, is from Nanping County. Great-grandfather Che Jun is Wu's satrap. Father Che Yu has always been a princess book. Nanping satrap is famous for knowing people. When I met Che Yin as a child, he said to his father, Che Yu, "This child will be honored to leave home and can study specially." Che Yin is diligent and knowledgeable. The family is poor and often lacks lamp oil. On summer nights, dozens of fireflies are packed in white silk bags for lighting and reading, day and night. Old, beautiful, smart, agile, wise, very prestigious in the village. When Huan Wen made the secretariat of Jingzhou, he asked Che Yin to do it. Because he was good at distinguishing right from wrong, he was particularly valued. It was cited as the main book, and later moved to other places to explore western history, so it became famous in the court. At that time, only Che Yin and Wu Yinzhi were famous for their poverty and erudition. Che Yin is also good at enjoying parties. At that time, every time there was a grand event, Che Yin was not there, and everyone said, "I am not happy without a lathe worker." The servant Xie An holds a banquet for Che Yin every day.

In the early years of Kangning (373), the court appointed assistant minister of Zhongshu, who was in charge of the inner government. Emperor Xiaowu once interpreted the Book of Filial Piety, taking Xie An as a servant, thinking that he was a minister, taking Bian Danban as a servant, thinking that Huang Menfu was an official, and taking Wang Yin as a mixed sentence. At that time, public opinion regarded this as a glorious event. Che Yin is too tired to serve easily. In the first year of the Prince (376 ~ 396), the imperial court added 100 students, and appointed Che Yin as Dr. Guo Zi. The following year, the court discussed the issue of Tang Ming, a suburban temple. Che Yin said: "The organizational system of ancient Tang Ming has always been difficult to understand, and the essence of music is harmony, and the essence of ceremony is respect, so simplicity is different from beauty, and so are musical instruments. Since there are different standards for the scale of small house architecture, why should we abide by its shape instead of carrying forward its fundamental adaptation to the times? The world is stable, thieves from all directions are eliminated, and then Tang Ming University can be overhauled. " At that time, the court followed his advice. Che Yin moved to a title of generals in ancient times, worked too hard, and was promoted to Linxiang Hou, leaving his job due to illness. Soon, the court appointed him as a general. At that time, Wang Guobao flattered Wang Sima Daozi of Huiji, coaxed him, made Sima Daozi prime minister, and gave him special treatment. Che Yin said, "This is a courtesy for Zhou Chengwang to respect the Duke of Zhou. Now the emperor is in his prime, and unless he is a young king, he can't be a duke of Zhou. How can he be the Duke of Zhou? Prestige is not commensurate with reality, so it is not appropriate. This will definitely go against the wishes of the emperor. " Therefore, Che Yin refused to deal with the matter because of illness. After Wang Guobao and others played Shubiao, Emperor Wudi was furious and rewarded Che Yin.

In the early years of Long 'an (397), the court appointed Che Yin as the magistrate of Xing Wu with a salary of 2,000 stone, but Che Yin refused to accept his illness. The imperial court made him a general of the auxiliary country and Yin Danyang. Soon, he was appointed as the official minister. It's Sima Yuan Xian's fault. Che Yin and Jiang Ji privately told Sima Daozi that they were going to tell the emperor, and the story leaked out. Sima Yuan Xian forced Che Yin and others to commit suicide. Che Yin died soon, which deeply regretted the court.
