The Challenge Cup is a China University Student Entrepreneurship Plan Competition sponsored by the Ministry of Education, which aims to encourage and support college students' innovation and entrepreneurship, and improve their innovation and entrepreneurship ability and practical ability. Since 1992 held the first Challenge Cup, it has become one of the most influential entrepreneurial competitions in China universities.

The Challenge Cup is held every two years. In other words, it is held every two years. The setting of this cycle not only considers the periodicity of college students' entrepreneurial projects, but also considers their study and life rhythm. Two years is enough time for college students to complete the planning, implementation and promotion of an entrepreneurial project without affecting their study and life.

Although the Challenge Cup is held every two years, the time node of each session is not fixed. The specific schedule needs to be adjusted according to various factors. For example, the 20 19 Challenge Cup was originally scheduled to be held in June, but due to the COVID-19 epidemic, it was finally postponed to 1 1.

This also shows that the holding time of the Challenge Cup is not absolutely fixed and needs to be adjusted according to the actual situation. In addition to the biennial cycle, the Challenge Cup has another feature, which is divided into two stages: the national competition and the global competition. The national competition is held in China and the global competition is held abroad.

The winning projects in the national competition can be promoted to the global competition, and the projects participating in the global competition come from the entrepreneurial teams of college students from all over the world. The time nodes of the national and global competitions are not fixed and need to be adjusted according to the actual situation.

Generally speaking, the Challenge Cup is held every two years. The setting of this cycle takes into account the periodicity of college students' entrepreneurial projects and the rhythm of study and life. The time node of the Challenge Cup is not fixed and needs to be adjusted according to various factors. The national and global competitions of the Challenge Cup also have different time nodes, which need to be adjusted according to the actual situation.
