On December 17, 1720, Emperor Kangxi sent troops to Tibet. Xizang has been the territory of China since ancient times, but it has been invaded by foreign armed forces many times in history, threatening the lives of the local people, normal religious activities and exchanges with the mainland. During the Kangxi period of the Qing Dynasty, Emperor Kangxi sent troops to Tibet many times, but he failed repeatedly. On December 17, 1720, Emperor Kangxi sent troops to escort the Sixth Dalai Lama into Tibet. He was supported by the people of all ethnic groups in Sichuan, Qinghai, and Gansu. He fought against the Junggar people all the way. Finally, he entered Anzang and won. It took 20 years. A series of complex contradictions and wars broke out, which finally subsided and settled down in Xizang. From then on, the Qing Dynasty further strengthened its management of Xizang.
