What happened to the Han people who were smuggled into the northeast by Manchu?

When Nurhachi was a slave, most of the Han people in Northeast China were slaughtered except a few slaves. After Huang taiji ascended the throne, he changed his strategy, reused Han officials, lured Ming generals, invaded the population several times, and formed the cannon fodder army "Han Eight Banners". The Ming army that surrendered after entering the customs was also incorporated into the "Eight Banners of the Han Dynasty", which laid the vast majority of the territory for the Qing Dynasty. The status of these people is very different from that of ordinary Han people, and now they are part of Manchu.

Northeast China was regarded as "the land of Longxing" by Manchu, and was isolated from the mainland by Manchu rulers as a retreat in the future. The surrendered Han people moved to the mainland, and the adherents of the Ming Dynasty were bloodily cleansed, leaving Manchu and some ethnic groups close to them.

Later, Shandong was sparsely populated, and the lower reaches of the Yellow River were affected every year. A large number of Shandong people who could not survive sneaked into the northeast from the sea. The Manchu government was unable to provide disaster relief and was afraid of the riots of the victims, and gradually acquiesced in this behavior. In addition, tsarist Russia invaded the northeast like nobody's business, and Manchu changed its mind to encourage immigrants to go through customs. Today's Northeast people are mostly descendants of Shandong people.
