After Neo-Confucianism, the study of contemporary Confucianism became more diverse. Its original uniformity was replaced by diversity. During this time, however, Post-Confucianism became increasingly prominent. Post-Confucianism comes from a post-modernist context and was influenced by a post-modernist ideological mode, and so its appearance was inevitable. It was also closely linked to significant philosophical issues after the change in times, and therefore questioned and challenged Neo-Confucianism which was based on a pattern of modernity. Post-Confucianism represents a new trend in the contemporary development of Confucianism. From a cultural point of view, this essay systematically investigates three internationally renowned schools of Post-Confucianism and their backgrounds, noting their similarities and differences, examining their significance, and determining their meaning. By doing so, it intends to outline an intelligible framework for this academic trend and highlight the significance of Post-Confucianism for the development of contemporary Confucianism.
