Bo-ling Chang, a famous educator in modern China and the president of Nankai Schools, with the support of teachers, students and people from all walks of life, called for and put into practice “Gongneng” education, which incorporated the essence of Eastern and Western ideology and culture and inherited the good part of Chinese tradition. He empowered himself and put forward targeted solutions to cure the chronic diseases of the Chinese people, such as “ignorance, weakness, poverty, disunity and selfishness.” He devoted more than half a century's painstaking efforts to promote modern education with equal emphasis on “morality, intelligence, physical and social education.” He spread science and civilization, and took the development of Chinese history and Chinese learning as an educator's responsibility, in the hope of rebuilding the spiritual life of the Chinese people. He was highly praised by Chinese and foreign educators for his contribution and achievements. Under the goal of serving the society and benefiting the people, Nankai series of schools set up by Bo-ling Chang were aimed at making the educated understand that learning meant not to enslave others but to serve more people. Everyone should have both the spirit of and the ability to sacrifice for the public interests and dedicate to the Chinese nation in times of crisis. Bo-ling Chang's effort in rebuilding Chinese people's spiritual life is still of modern value and benefits to the students of the present age.
