Professor Cheng earned his PhD in Culture and Religion from the Chinese University of Hong Kong in 2006. His research focuses on early Daoist thought, the history of Daoist ideas, and intellectual history during the Han Dynasty. Adopting a perspective that views religion in terms of faith, he employs methods in textual and intellectual history to analyze Daoist classics within their ancient cultural contexts, thereby contributing to an academic understanding of Daoism in Chinese cultural history. Professor Cheng also teaches a range of courses on Daoism and religious studies, including Daoist history, Daoism and folk religion, and the principles of religious studies.
