Hope Cup Mathematics Invitational Tournament has been held for more than ten times since 1990. 10 For many years, the organizers have insisted that the contest is open to most schools and students. Every link from proposition, award to organization revolves around one purpose: to stimulate middle school students' interest in learning, cultivate their self-confidence and constantly improve their ability and quality. This activity only involves Grade One, Grade Two, Grade One and Grade Two, not Grade Three and Grade Three. It is not repeated with the Olympic Games, linked with the senior high school entrance examination and college entrance examination, and does not increase the burden on teachers and students, so it is welcomed by teachers and students.
