It has been confirmed by Russian mathematicians, and two in our country only check for leaks and fill gaps, which means that Russian mathematicians have confirmed most of them and given a clear direction, while two in our country have made a little supplement to this idea. These world math problems need many years to be fully verified and supplemented, just like when we ordinary people do problems in high school, thinking is the most important. China has been feeling inferior for hundreds of years, and the world's top problems in the scientific community have not yielded any results. I feel that there are too many problems in the domestic education system. For example, mathematics can often win the Olympic number, but no math prize like Fields can be won in China. I feel that our educated students can do problems, but they can't think about innovation independently. There are still too many shortcomings in China, such as the ranking of disciplines contributing to the world's science and technology, where China is less than 200, and there are many problems. Society has not invested enough in theoretical science. If you are too eager for quick success, you can be eager for quick success, even in film and television. See if American directors can make a film for more than ten years. . . . All walks of life in China seem to be eager for quick success and instant benefit.
