Why are there still these "best people" in Xining, Qinghai?

Qinghai has always been backward. It's been a while since you left here. Of course, you can't compare with the people outside here. The quality is not at the same level at all. However, the quality of people in Xining, Qinghai Province is also improving, but it is worse than other places, and most of them are uneducated and have not "metabolized" out of the social circle ... Among the mainstream people, there are many uneducated people ... This is the main factor, and people who like to dress neatly.
