Introduce Yi Yin.

Yi Yin, a minister in the early Shang Dynasty, was born in Kongsang (now south of Chenliu Town, Kaifeng City, Henan Province) in the 6th century BC. "Lu's Spring and Autumn Annals" said that a baby was picked mulberry by a woman named. My mother lives in Yishui, and her name is Yi Yin. Yin, Yaya. It is said that Tang turned it into the best place in the world. Before he became an official, he worked hard in the "wild land" (now Shenxian County), and later assisted in the establishment of the Shang Dynasty, governing the officials and the people for more than 60 years, becoming the "three generations of veterans and a generation of sages" of the Shang Dynasty. Woding, the Shang emperor, died in Bo (now south of Cao County, Shandong Province) at the age of 100. According to "Old Records of Shenxian County", the west of Wangdali Village, Shenting Town, Shenxian County was the cultivated land in Yi Yin that year, and there was Shenting in ancient times. 17 16 years (fifty-five years of Qing emperor Kangxi), the governor of Dongchang ordered the monument to be built here, and personally wrote "Shenting-Yingeng place", which still exists today.

Shangyiyin

It's an abandoned child that the Shen family found in the mulberry forest. Because his foster mother lives near the water of Iraq, she takes water as her surname. Although Yi Yin is short and unattractive, he is resourceful, smart and ambitious. At that time, King Xia Jie was tyrannical and cruel, abusing people's power, making the fields barren and the people miserable. Seeing that the Xia Dynasty was unlucky, Yi Yin approached Shang Tang with superb cooking skills and persuaded him to hold high the banner of righteousness to take the place of Xia Jie. After talking with Yi Yin, Shang Tang thought it was a brief encounter, and immediately named Yi Yin "Aheng" (Prime Minister). Under the management of Shang Tang and Yi Yin, Shang Tang's power began to grow, and he wanted to attack Xia Jie. Yi Yin suggested that Shang Tang stop paying tribute to Xia Jie and see how Xia Jie could test Xia Jie's strength. Xia Jie was really angry. He summoned the troops of September 1st to attack the merchants. Yi Yin immediately advised Shang Tang: Xia Jie can still mobilize troops, and the time is not ripe for us to attack him. So Shang Tang paid tribute to Xia Jie again. Yi Yin saw that the time was ripe and stopped paying tribute to Xia Jie again. But this time, due to Xia Jie's atrocities, he failed to mobilize the army, so Yi Yin suggested to Shang Tang to arise.

Shang Tang quickly defeated Xia Jie's army and exiled Xia Jie to Nanchao. The Xia Dynasty ended, and the vassals supported the virtuous Shang Tang and established the Shang Dynasty as the "emperor".

Shang Tang and Yi Yin work closely together to care for the people. Be loved by the people. After Shang Tang's death, Yi Yin assisted his descendants until Shang Tang's grandson, Tai Jia, became the Shang King and Tai Jia was tyrannical. Three years later, Yi Yin demoted Tai Jia to the Children's Palace, where he was a regent and accepted the worship of the governors. Emperor Taijia lived in Tonggong for three years, repented and reformed. So Yi Yin pulled Taijia out, returned it to the government, retired and returned to his hometown. After Tai Jia returned to the throne, he carried forward the virtue of Shang Tang, loved the people diligently, joined the historical princes, and achieved social peace.

After Yi Yin's death, Divodin (son of Tai Jia) was buried with the emperor's gift.

Note: The above is taken from Historical Records. There is a question: Why did Yi Yin report his old age to his hometown immediately after Tai Jia returned to politics? Is he really worried that Taijia will get better? I'm afraid Tai Jia forced him to leave.
