December 9 Chorus Contests are designed and organized to integrate patriotic education with the school’s development through various events on important commemoration days in order to enhance students’ sense of responsibility and mission. The activities include the 90th anniversary of the CPC’s founding, chorus contests in memory of the patriotic students’ movement in December 9, 1935, and meetings commemorating the 1911 revolution that toppled China’s last feudal government and the 9•18 Incident in 1931 that marked the Japanese occupation of Northeast China.
