I want to say that this is a kind of accumulation and the result of experience. Mathematics in the United States may really be much better than that in China, as we saw on the Internet. Their math level is really low, but their school motto is world-class, surpassing China for many years.

In fact, in my opinion, this is incomprehensible. You should know that the national strength of the United States is very strong, and scientific research is also very important. It can be said that American scientific research has many years of experience, and their accumulated experience enables them to develop very powerful things. But our national strength is so strong that scientific research has only begun in recent years. Although the distance with the United States is being shortened, there is still a long way to go.

For example, it's like people have accumulated a certain amount, which is equivalent to accumulating a lot, and we are later pursuers, so don't worry, maybe we can make some scientific breakthroughs in time.
