At that time, when Xia Jie was in power, the Xia Dynasty countries gradually declined, and the contradiction was extremely sharp. Tang took the opportunity to attack and destroy more than a dozen small countries and tribes such as Ge (now Ningling North, Henan Province). Followed by Ke Wei (now southeast of Hua County, Henan Province), Gu (now southeast of Fan County, Henan Province), Kunwu (now Xu Changdong, Henan Province) and other small countries. After the war of 1 1, the world was invincible, which made the Xia Dynasty unprecedentedly isolated, took advantage of the Youjia rebellion, defeated Xia in the Ming Dynasty, and destroyed Xia in one fell swoop. Because Shang Tang destroyed the summer by force, it broke the argument of Yongding King. Since then, China has changed dynasties in this way, which is called "Shang Tang Revolution" in history. After the establishment of Shang Dynasty, the Tang Dynasty reduced the internal levy, encouraged production and appeased the people, thus expanding the ruling area, affecting as far as the upper reaches of the Yellow River, and all the Bianqiang tribes came to pay tribute.
