The National Mathematics League is actually evaluated in your province. One to fifty people in the province are the first prize. The people who make the proposition are uncertain, some are professors in your province, and some may be people in the mathematics proposition group of the national college entrance examination, which is different every year. Moreover, it is difficult to know who will make the proposition before there is an exam. After they finish the problem, they eat, drink and have fun there every day, but they can't get out. So the person who can name you is either lying to you or related by blood. Think about it, this kind of information, you use the score of 200 Baidu, can others tell you? They are usually bought with money, hehe.
