Why does a very large area in Dadong District of Shenyang move?

The northeast is not so prosperous, and it is far from the outside. It used to be a Shandong-Northeast migration tide, but now it is a Northeast-South migration tide, and the rest of the Northeast people. . . It's not so good anyway . Northeasters who leave the Northeast have a general reputation abroad. It is common to make trouble and brag. Bragging is really common. There are many things. I don't know whose business I am. I will tell you about it as if I were there. Like what happened to him, it always sounds hypocritical. Sooner or later, something will come out to cheat others. In Beijing and Guangzhou, many Northeasters have seen conflicts in the streets. Although there are not many street conflicts on the whole, I have only seen conflicts in big cities a few times, but two or three times they are all from the northeast.
