There is a general skepticism in Chinese society that Daoism does not exist as a religion and therefore, the existence of Daoist music is even more skeptical. However, people of Fung Ying Seen Koon, a Daoist temple in Hong Kong, PRC, make great efforts to establish Daoism as a more institutionally‐recognised religion and to promote Daoism to the public. Their efforts have made Daoism recognized as a distinct religion. One of their efforts is the establishment of Daoist music, which is institutionalised and formalized. It makes Daoism “a religion”. In other words, Daoist music exists and therefore, Daoism exists as a religion. Explanations of music are based on understanding. Understanding music does not merely mean “knowing music” in terms of the neuro- sensory experience of music including listening to, feeling and recalling music. It also means “knowing about music” such as knowing the title, the composer, the musicians, the historical background and even the genre of music. Knowledge of music helps people define music for themselves. At the same time, music that is defined in a certain way also defines the group of people who appropriate and define that particular music. In this article, music defined as Daoist music acts as a symbol of Daoism to define its appropriators as Daoist.
