As for the profound statement about high school mathematics in China, there is absolutely no need to compare it with university mathematics, just compare it with Europe and Japan. China high school mathematics is not difficult at all, and it is getting easier and easier. Mathematics before undergraduate courses in the United States is relatively simple and is often laughed at all over the world. Please don't take America as the standard and always look down on it.

Some people envy the French college entrance examination questions, saying that they have depth. Believe me, anyone who dares to ask such a question and block a wooden bridge in China will be drowned by the saliva of the parents of the students. No matter what is useful, it is also a waste in this case.

The difficulty of basic mathematics in China can be superb, but if the quality is still at the bottom, it will be China, not the United States, who will be laughed at.

I agree with @ Zhang Yumeng, and then I think it's unkind to criticize without mentioning suggestions.

My specific suggestions include: the difficulty depth of senior high school education cannot be reduced, the evaluation system should be changed, the status of technical schools in vocational schools should be improved, and various ways of higher education should be provided, so that a single subject will no longer be an obstacle to anyone's success. Ideally, if you learn well and continue to deepen, everyone can continue to receive education, but if you don't learn well.
