Why did the Qing dynasty often put people in the northeast, the birthplace of Manchu?

There are two meanings: one is to punish evil and promote good, so that people who have committed crimes can leave their homes and suffer hardships, surrender themselves to the customs, feel sorry for themselves and be washed away by the wind and sand; The second is to improve the living conditions of human beings for the hometown of the Qing royal family.

During the Qing Dynasty, there were many remote and backward areas in China. Why didn't the Qing dynasty exile criminals to other places for reform, and preferred Ningguta in the northeast? The intention is obvious, that is, Ningguta is the birthplace of Manchu and the hometown of the Qing royal family. Criminals came here not only to reclaim land, build bridges and roads, and change the face of the hometown of the Qing royal family, but also to starve and become slaves of local officials and Manchu to show the glory of their ancestors.

In fact, Ningguta is a city name, which was the place where criminals were exiled in the Qing Dynasty. After the establishment of General Ningguta, it was the predecessor of Jilin General. Ningguta is a remote area. In the past, the environment here was harsh, the climate was abnormal, nothing grew, and the grain was not long. It is very suitable for the reform of criminals. It is not a tower, but why is it called "tower"? According to legend, six distant ancestors of the Qing royal family once lived here. The Manchu language is called "Gu Ning", a pagoda, which was called "Gu Ning Bao Pagoda" in ancient times.
