Why did the Manchu government prohibit Han Chinese from entering the Northeast? What's the secret in it?

After Manchu entered the customs, a large number of Manchu people moved into the customs, and the population outside the customs withered. Because the Manchu people are not confident, they default that the northeast is their own rear area. If they can't get along, they can go back to the northeast. Therefore, the northeast has always maintained the traditional Manchu lifestyle, and other ethnic groups are not allowed to enter. It was long regarded as "the land of Longxing" in the Qing Dynasty, and the ban on the Northeast was quite strict, and it was not opened until the end of the Qing Dynasty.

After the Qing army entered the customs, it was actually Dourgen who was in power during the period. 1644, dourgen ordered the Han people not to enter the northeast, that is, not to enter the "land of Longxing", and the jurisdiction was very strict. And set up the jurisdiction of Shengjing, Ningguta and Heilongjiang General to ensure that the ban can be effectively implemented.

However, it is inevitable that there will be famine in the pass, and there will be a large number of refugees, some of whom are called "going east", but in fact they are running northeast. Because there was a ban in the northeast at that time, it was not allowed to move to the northeast without permission, so there was a saying of "going to Kanto", which was actually a secret or forced entry into Kanto to make a living in the northeast.

However, during the Qing Dynasty, northern Russia constantly invaded the northern territory, and many places in Longxing, such as the outer Xing 'an Mountains, were actually handed over to Russia, which was also quite depressing. Therefore, in order to ensure the safety of the northern border, it is necessary to make it have enough population before the Han people begin to immigrate to Shanhaiguan, and then the population will gradually increase.

Therefore, we see that the Manchu people banned Han Chinese from entering the Northeast just to give themselves a retreat and return to the Northeast to maintain their rule when they could not rule the customs. However, in order to ensure that Manchus in Northeast China occupy the dominant position and maintain the ruling tradition, the Han nationality should not be allowed to influence the satisfied subject and culture, and the Han nationality should not be allowed to enter. Therefore, the Northeast became a "land of prosperity", and Long Mai of the Qing Dynasty was here.
