Gala as a widely popular form loved by college students brings together a variety of art forms, with its rich content and distinctive style, which enables viewers to watch different forms of performance in a short period of time. Universities gala melts artistic, entertaining and educational role in one and combines ideological guidance with lively art forms to actively promote the construction of campus culture, disseminate correct, positive and healthy ideas and culture, show the campus features with contemporary characteristics to society, create a healthy educational environment and establish a good image of college.展开更多
