It seems that there are not many gold medals in Jinan team's Hua Shu Cup (China Mathematical Gold Cup, sponsored by China Optimization Method and Economic Mathematics Research Association and China Education Association, the first national primary and secondary school mathematics competition); Jinan team's campus discipline innovation competition (including mathematics, Chinese and English, sponsored by China Education Association and the "Eleventh Five-Year Plan" research group of the National Social Science Fund, but going to Hong Kong to participate in the Asian regional finals every year) is better; The Hope Cup (sponsored by Mathematics Tiandi Magazine and China Optimization Method and Economic Mathematics Research Association) has a lower gold content than the first two, and the first two are also used in primary schools to evaluate three good students, but the Hope Cup is slightly worse and is not recognized in Jinan schools; AMC (sponsored by the American Mathematical Society, the number one Mathematical Olympiad in the world, which is highly recognized by the top 500 applicants from Harvard, Stanford and Princeton, and its score is more difficult than SAT, but it is extremely difficult) is a competition introduced and popularized in chinese mathematical society. The youngest sixth-grade primary school students take AMC8, the third grade and above take AMC 10, the second grade and above take AMC 12, and senior high schools enroll students in provincial experimental middle schools and Peking University. Generally, those who have participated in the first prize and second prize of China Digital Cup and Campus Discipline Innovation Competition in Jinan are recommended to participate in AMC competition.
