Shang Tang's benevolence touched heaven and earth and gave him a hundred years of life. However, the gods may not act justly, and they have also done regrettable things to Shang Tang. Shang Tang made Taiding the crown prince and sent him to govern the barren small cities in the west, hoping that Taiding would train himself there. Taiding was diligent and talented, and seven years later, Bien Xian had become a prosperous city second only to the capital at that time. Shang Tang was satisfied with Taiding's achievements and decided to summon him back to the capital to prepare for the succession. Taiding wrote that the temple being built to worship ancestors and gods in Bienham had not yet been completed, and he requested to return to the capital after completion. Shang Tang was relieved to agree, however, he did not expect that this promise would turn out to be Taiding's bad luck.
On a sunny day, the people of Bianxian worked happily, but they were suddenly attacked by violent storms, lightning and thunder. The immortals and the water monarchs fought privately in the sky, and after the battle, the border county town and the people were wiped out, and the prince Taiding was also unfortunately killed. Shang Tang was furious at the loss of his beloved son, and ordered the destruction of all temples and totems in the world. Yi Yin advised Shang Tang not to do this, and at the same time complained to the Emperor of Heaven to expose the crimes of the immortals. The Emperor of Heaven attached great importance to this matter, degraded the immortals, and promised a hundred years of good weather and good weather. However, Shang Tang was heartbroken and old, so he handed over the government affairs to Yi Yin, and wept bitterly over Taiding's grave all day long.
A hundred years later, Taiding's younger brother Wai Bing succeeded to the throne, and Yi Yin continued to be regent. Wai C and Tai Ding have a deep relationship, but Tai Ding's death has a huge impact on Wai C, and he is sad and sad, so he died after only three years as king. Zhongren took over, and Yi Yin was also regent. Taiding's son Taijia succeeded to the throne, and at the beginning he was loose and could not distinguish between right and wrong. Yi Yin wrote "Wanton Life" to persuade him how to distinguish between right and wrong, and at the same time wrote "The Queen" to tell him about the laws and sacrificial system of the Shang Tang period. With the assistance of Yi Yin, Taijia ruled cautiously for three years, and the Shang Dynasty gradually prospered.
However, Taijia indulged in power, harsh criminal laws, extravagant architecture, and even changed the sacrificial system. Yi Yin realized that the situation was grim, returned to the court, and advised Taijia. Taijia was obsessed, and finally Yi Yin decided to depose Taijia and exile him to Tonggong. Taijia felt deeply guilty and vowed to change himself and Xi learn from Shang Tang. In Tonggong for three years, Taijia's heart has become more and more determined, and his talents have been continuously improved.
Yi Yin led the minister back to Tong Palace to welcome Taijia back to the court. Taijia knelt down to worship Yi Yin, reflected and swore loyalty to the country and the people. After Taijia returned to power, the Shang Dynasty became even stronger. After Yi Yin delegated power, Taijia gradually matured, and the country prospered and stabilized. By the fourth year, Yi Yin decided to retire after believing that Taijia was already able to govern the country on his own. However, Taijia abused his power, the country had problems, and Yi Yin returned to the court again, and his advice was fruitless. For the sake of the tranquility of the Shang Dynasty, Yi Yin eventually deposed Taijia and exiled him to Tonggong.
