For a simple example, in some big cities, such as Shanghai. The education level in this place is definitely quite high. Not to mention how many key universities there are in this place, even their primary school, junior high school and senior high school teachers are certainly quite strong. But if a student is from Shanghai and a student is from Dabie Mountain, it is conceivable how different the educational environment they have been exposed to since childhood. Even if a person has the same IQ, their talents are the same. In different educational environments, the final result is of course different.
This gap will exist for a long time, and what we can do is to gradually narrow it. There are many different voices on the Internet. Why do they say that their enrollment scores in some areas are so low? Can the whole country be unified? This can't be done, at least in the short term, because of the educational resources in a region. Unlike another region, their enrollment scores are different, and the education level in different regions is also different. It is unrealistic to really let the whole country roll around. Don't complain too much. Where you are is the trend of that place. As long as you work hard, you are always better than the people around you.
Complaining is useless and won't change anything. Even if you say it's unfair and unfair, and you don't work hard, the final result will be that you won't be admitted to a university or a good university. But if you work hard enough, a better area can be admitted to a key university as long as you study 8 hours a day, but you can be admitted to a key university if you study 12 hours. When you work hard, you can change all this.
