In Shang Tang's later years, his sons fought fiercely for the throne. Eventually, Shang Tang's grandson Taijia succeeded to the throne and became the fourth monarch of the Shang dynasty.
Although Taijia is smart and promising, at the beginning of inheriting the throne, he made some mistakes because of his youth and vigor. He reused traitorous ministers, which led to chaos in the government and the misery of the people. At this critical moment, Yi Yin, a virtuous minister beside Taijia, appeared. He bitterly admonished Taijia, reminding him to keep a clear head at all times and not to be deceived by the glory and wealth in front of him. Eventually, with the help of Yi Yin, Taijia realized his mistake and began to work hard to rectify the dynasty.
However, the Shang dynasty's rule was not stable. During the reign of Taijia's grandson, the Shang dynasty was once again in turmoil. This time, the Shang Dynasty's enemies came from the north and were the powerful Ghost Fang tribe. The leader of the Ghost Fang tribe believed that the Shang Dynasty had declined and was vulnerable to attack, so he led a large army south to attack the Shang Dynasty. In the face of a powerful enemy, the Shang Dynasty army was defeated one after another, and the country was in danger.
At this critical moment, Taijia's grandson decided to appoint a general named Zhou. Although young but courageous, Zhou led the Shang Dynasty army to fight bravely against the enemy, and finally succeeded in repelling the attack of the Ghost Fang tribe. This victory not only saved the fate of the Shang Dynasty, but also made Zhou a hero of the Shang Dynasty. From then on, Zhou's status in the Shang Dynasty gradually rose, and he eventually became an important minister of the Shang Dynasty.
After this crisis, the Shang Dynasty began to regain its strength. Taijia's grandson realized that in order for the country to be stable for a long time, it was necessary to constantly reform and innovate. As a result, he began to implement a series of reform measures to strengthen the centralization of power, improve the combat effectiveness of the army, and at the same time vigorously develop economic and cultural undertakings. With the concerted efforts of the monarchs and ministers, the Shang Dynasty gradually regained its former prosperity.
