After Tang's death, he helped Tang's sons and. After Zhong Ren's death, he helped Tang's grandson, Tai Jia, become king, and taught Tai Jia to govern the country diligently with Tang's achievements and sudden death. However, after Tai Jia ascended the throne, he indulged in singing, dancing and drinking blindly, ignored political affairs, and took the lead in destroying the laws and regulations formulated by the Tang calendar. Yi Yin earnestly exhorted many times, but Tai Jia was indifferent. Seeing that Taijia is getting worse and worse, she will become the second Xia Jie. Yi Yin built a palace next to the tomb of Tang Yutong (now southwest of Yanshi County, Henan Province); Resolutely sent Tai Jia to live there, let him reflect, and Yi Yin was in charge of state affairs. This matter, history says "Yi Yin put too much armour". Tai Jia thought twice and finally repented. Three years later, Yi Yin personally carried the crown of the king and went to the East Palace to meet him back to Beijing and return to the National Government. He still took photos and carefully helped. Since then, Tai Jia has been diligent and loving the people, modest and prudent, and has become a wise monarch. Yi Yin was also very happy, and made three articles, including Tai Jia Xun, to praise him.
According to The Imperial Century, Yi Yin assisted the five emperors of Shang Dynasty all his life, and died at the age of 100 when Woding, the son of Tai Jia, was in office. It was foggy for three days when he died. In order to repay his loyalty and support to the Shang royal family, Woding buried him in Bo with a gift from the emperor. According to historical records. Justice. Broad ambition says that Bo is the northwest of Yanshi County (now the northwest of Jiangshi County in Henan Province).
According to the above records, because Yi Yin helped the Tang Dynasty destroy Xia Jian Shang and transform Tai Jia, he neither fooled the ridiculous king nor seized the opportunity to usurp the throne, which was sincere to the country. Therefore, later generations honored him as the first saint in the history of China, and regarded him as a model of people and ministers together with Lu Shang (Jiang Taigong), Duke Zhou and Guan Zhong. I don't know that Yi Yin died 1000 years later, during the reign of Sima Yan, Emperor Wu of the Western Jin Dynasty, an ancient book "Annals of Bamboo Books" was found in the tomb of the Warring States in Ji Jun County, which recorded: "Loyalty collapsed, and Yi Yin expanded its armor to stand on its own feet. Yi Yin acceded to the throne, seven years, Tai Jia attacked the child and killed Yi Yin; It is to set up his sons, Yiyi and Yifen, to restore his father's farmland and divide it. "
This caused an uproar. Yi Yin, who has always been highly respected, is not a saint, but a giant traitor who usurped the throne. Since then, the question of whether Yi Yin was a saint or a traitor has been debated by scholars of all ages.
One school thinks that the chronicle of bamboo slips describes the historical events in Xia and Shang Dynasties, which is quite reliable after textual research and has high historical value, so the statement that "Tai Jia killed Yi Yin" should be credible. Yi Yin's theory of reforming Tai Jia and returning to national politics is nothing more than the Confucian view of worshipping the past. Yi Yin was a traitor and was killed after usurping the throne.
Another school of scholars quoted classics and strongly refuted them. Among them, Cui Shu, a historian in Qianlong period of Qing Dynasty, is a typical representative. Regarding the statement that Tai Jia killed Yi Yin, he argued: In Mencius, "Tai Jia repented, felt sorry for the child, moved righteousness to the child, and returned to Bo after listening to Yi Yin's instructions for three years." "Tai Jiaxian, and vice versa, folk music." It shows that Tai Jia returned to Beijing after Yi Yin regretted his discipline. In Zuo Zhuan, there is a saying that "Yi Yin put too much armor in the picture, and the pawn had no complaints", which means that after Tai Jia was reset, he still took Yi Yin as the picture and had no complaints about Yi Yin, indicating that he did not kill Yi Yin; After Yi Yin was buried by Woding Li, there was a Woding in Shangshu, which praised Yi Yin's merits and showed that Yi Yin died a fair death. After Tai Jia killed Yi Yin, he made his son Yi and Yi powder as the phase, and killed his father and made his son as the phase, which is not credible.
Cui Shu believes that killing the king and the Lord is common in the Warring States period, and the world is corrupt, and everyone forgets righteousness. Due to the influence of this trend, Yi Yin's behavior of wearing too much armor evolved into the theory that Yi Yin was killed on the throne. He even wondered whether the author of Bamboo Records had copied the historical data of Yi Yin's "Fang Tai Jia". He insisted that Yi Yin was a "saint" with a "broad mind and a bright future".
Since the annals of bamboo books unearthed in the Western Jin Dynasty 1700 years ago, both views have their own opinions, but neither can produce strong circumstantial evidence, and it is difficult for anyone to convince the other side. It seems that whether Yi Yin died of natural causes after returning to the imperial court, or was killed after abolishing the Lord and usurping the throne, and whether he was a saint or a giant traitor, we have to wait for historians to dig deep into historical materials and make further textual research.
