Wen Zi, Bi Gan and Yi Yin were the important assistant ministers in Shang Dynasty.
Yi Yin is famous as the founding minister.
Yin's original name, Oracle Bone Inscriptions called it Yi, called it Yi. According to legend, Yi Yin was born near Yishui, and went to Shen You's home as an adult to make a living by farming. Although his position is very low, he is worried about the world. He saw that the Xin family had a gentleman and virtue, and wanted to persuade him to rise up and destroy the summer. In order to get close to Shen Guojun, he volunteered to be a slave and served as Shen Guojun's personal chef. The monarch discovered his talent and was promoted to the position of managing meals. After long-term observation, Yi Yin finally found out that there were Shen and Xia surnames, both of which were in the back, so it was difficult to sever the blood relationship. Besides, at that time, there was a small country with few people and weak troops, which was not enough to undertake the heavy responsibility of destroying summer. Only soup was the ideal candidate, so I decided to go to soup. At that time, Tang married Xin's daughter as a princess, and Yi Yin volunteered to be his wife and accompany him to do business. He analyzed the general trend of the world and the way of governing the country, and advised Tang to undertake the task of destroying the summer. From this, Tang knew that the foreign demon had the ability to learn from heaven and earth, so he liberated him from slavery and became the highest ruling minister. Yi Yin was not only the founding father who helped Tang win the world, but also the hero of the later three Shang kings. Therefore, Yi Yin was listed as the first of the "old ministers" in Oracle bone inscriptions, and was ceremoniously sacrificed, not only with Tang, but also by himself.
