What would happen if the Ming dynasty immigrated to the northeast in large numbers?

From the early years of the Republic of China when Duo Yan Sanwei surrendered to the Ming Dynasty, the Ming Dynasty has been constantly migrating Han people to Liaoning (you have come, there will be wasteland for you, will you come? ), in the late Ming dynasty. There are already millions of Han people in Liaoning!

It is also because there are many Han people in Liao country that the Ming Dynasty ruled in Liao country for hundreds of years!

But there is an egg to use. The slave owners who emerged from Changbai Mountain defeated the powerful Ming army by relying on tens of thousands of people of their own nation! Then the policy of "five fights of rice" was implemented to slaughter the Han people under its rule. . After Tu, Tu and Tu were killed, only one million people were under the rule of slave owners, and 500,000 to 600,000 Han people sought Mao's shelter in Dongjiang Town! After the death of the slave owner, Huang Taiji came to power, changed his previous policy, treated the Han people well and protected their property. Then 500,000 to 600,000 Han people in Dongjiang Town returned to the embrace of the Qing Dynasty (mainly because the Ming Dynasty killed Mao, and the food supply in Dongjiang Town was cut off before, so the Han people could not live and lost their sense of belonging to the Ming Dynasty).
