Comrade Xu Teli's life is a textbook of modern revolutionary history that can educate people. The road he traveled is also a glorious road for the older generation of revolutionary intellectuals in China. Taking patriotic feelings as an ideological opportunity, Xu Teli changed from believing in Kang Youwei and Liang Qichao to being a disciple of Mr. Zhongshan. From being obsessed with "saving the country through education", he turned to favor the new Three People's Principles and became the left wing of the Kuomintang. Finally, under the practice of revolutionary struggle and the education of the Party, he believed in Marxism-Leninism, and believed that only socialism could save China. He grew from a radical democrat to a staunch proletarian vanguard fighter and an outstanding people's educator, and contributed his whole life to the national cause and people's interests. As a brave soldier of the democratic revolution, Comrade Xu Teli made many contributions to the revolution of 1911 and the development of education in Hunan as early as his youth. This is the great beginning of his extraordinary life.
