When did Xinjiang and Tibet belong to China?

During the Yongzheng period of the Qing Dynasty, Nian Gengyao defeated Rob and hid Tenzin, and twenty thousand Han troops entered Tibet. This is the first time in history that the troops of the Central Plains Dynasty have been stationed in Tibet. Yong Zhengdi has set up a minister stationed in Tibet and placed officials in the leadership of Tibetan Lamaism. This is the real meaning of designating Tibet as "the region of China". Since then, the government has issued policies to support immigrants, and a large number of Han people from Yunnan and Sichuan immigrated to Tibet in the name of doing business, which really became a region of the country. Tibet used to be independent. Tibet is called Tubo, and its relationship with the Central Plains Dynasty is similar to that of North Korea. When the Central Plains dynasty declined, Tubo would also take the opportunity to plunder Sichuan with cavalry. However, after the establishment of the Minister of Tibet, Tibet no longer had independent leadership and became a province.

Xinjiang is closer. Xinjiang, known as the Western Regions since ancient times, is a regional name. There are hundreds of countries in the western region. In the hundreds of years' war between Qing Dynasty and Gerdan, the western countries were occupied by Gerdan, until the Qianlong period, Gerdan was completely defeated and the Zhungeer khanate perished. Gan Long was overjoyed. He wrote down the word "Xinjiang" and asked people to leave that day and take it to Yili. Local officials dare not neglect, and Xinjiang has become the unified name of all countries in the western regions. Since then, the Western Region has become a province of China. Gan Long established Xinjiang Shangshu and Ili General to monopolize Hetian jade in Xinjiang.
