When did the Han people start to settle in Xinjiang on a large scale?

Large-scale immigration has been divided into several times, far from being mentioned. In modern times, during the Qianlong period, he defeated Da Ge and Zhuo and moved to Xinjiang with a large population. Now the Xibo nationality (Jurchen nationality) in Xinjiang passed at that time. After the September 18th Incident, the Northeast Army withdrew from the Northeast and a large part of it came to Xinjiang, which is why Sheng became the chairman of Xinjiang Province.

The latest one, of course, was the Production and Construction Corps after liberation.

The development of Xinjiang is not the achievement of one country, but the result of the joint efforts of many brother countries.
