At present, more than half of the residents in Beijing are either aborigines or former Beijingers, all from other provinces in China. Later, they came here for various reasons, but their education level is basically not low, especially in the past two years, you can settle down here. In the past five years, you should know exactly how high the housing prices in Beijing are. If you don't have any education level, and then your ability is not particularly outstanding, you can't afford to buy a house in Beijing at all, and naturally you can't settle down and become a Beijing resident.
The population structure is very complicated, but Guangdong ushered in a rapid population growth in 10 years before the reform and opening up in the last century, because there were many labor-intensive industries in the southern region at that time, which was where these foreign factories contracted. Although the salary is not particularly high, for many uneducated people, it is much better to suffer a little than to farm at home and get a stable salary, so many people went to that place, but it took a long time.
And the educational resources in Beijing and Guangdong are different. Beijing has educational resources in almost all cities in China. Ranking 1, there is not much difference in educational resources between Beijing and Shanghai, but Beijing is still slightly better, not to mention other places, and the background is still lacking. Therefore, with more educational resources, you can go to a better university with the same score, and there are more people who are naturally literate with a slightly lower score.
