Mr Tang Chun-I taught at a number of universities including Sichuan, Huaxi, and National Central. In 1949, he came to Hong Kong to establish New Asia College with Ch’ien Mu and Zhang Pijie, and between 1950 and 1954, he hosted public lectures on Chinese culture and scholarship. After the founding of the Chinese University of Hong Kong, he became the founding chairman of the Department of Philosophy and the first Chair Professor.

Tang dedicated his life to the reconstruction and development of humanism. Immersed in Eastern and Western philosophy, he was rooted in the study of Chinese sages and their moral teachings. His works Experiences of Life, Continuation of Experiences of Life, and Establishment of Moral Self offer profound and subtle insights into life. His six-volume work Original Principles of Chinese Philosophy systematically interprets traditional Chinese philosophy and periodically proposes new interpretations that can be reconciled with interpretations of other schools of thought. His last major work, Existence of Life and the Realm of the Mind, published in 1976, was a synthesis of his lifelong learning and thinking, marking the completion of his philosophical system.
