The difference between north and south is also related to the region. The northern region is vast, broad and cold, so northerners have formed a rough and bold character and body shape, while southerners are warm and warm, so they are more meticulous and gentle.
I think the same is true of education in mainland China and coastal areas. Countries or regions with many coastal areas are basically ahead of the mainland in economy, because coastal areas can be more easily exposed to the vast overseas world, and it is easier for people from overseas to engage in trade and cultural exchanges, such as fairs, such as preaching. Therefore, in this natural process, with the economic development of coastal areas, their cultures are constantly being absorbed and integrated, and eventually they must be advanced in the mainland, because they are in line with and communicate with the world before the mainland.
Because of the rise of economy and culture, their education must also be advanced in the mainland. Do you think, 100 yuan, high education, my education will teach you how to earn 1 yuan, and teach you low education?
I'm not saying that education in mainland China is just the bottom. I'm just making an analogy. The mainland is indeed inferior to the coast in economy, culture and education. What you said is different. In fact, you think that education in the mainland is relatively rigid, while education in coastal areas is more flexible. In fact, this is caused by the economic and cultural gap I mentioned above.
You can ask if you don't understand.
