Principal Xu Jiancheng has advanced schooling concepts. In 2015, the Principal Training Center of the Ministry of Education held the "Xu Jiancheng Educational Thoughts Research Forum" in Nanchang. He believes that the school should pay attention to people's "life and health, survival and development, life and happiness" and he advocates the integration of the "multiple intelligence" theory and the "three-life education" concept. He holds the view that we should cultivate students on the five aspects of "moral, wisdom, physical, beauty and labor". Simultaneously, we need to educate people "all-round, whole-process, whole-region" and "cultivate responsible modern Chinese." During his tenure as the president of Nanchang No. 3 Middle School Education Group, he actively responded to the Group Education Strategy of the Municipal Education Bureau, and worked hard to practice the concept of "People's No. 3 Middle School", so that quality education can benefit more people.
