China provides a platform for students to showcase their talents in mathematics. It encourages learning of mathematics among students. It helps identify talented students and to provide them. The answer scripts of each participating team will be marked by the team leader and the deputy leader. The team leader will later present the scripts of their contestants to the coordinators. been two students who entered the national team and received Gold Medals at IMO. Since 1986, the china team has never had a female student. In order to encourage more female students to participate
