Taoist masters and true people were the names the Daoists used to address high-level cultivators. However, there were some differences between them. The term 'heavenly master' was used in the Taoist tradition to refer to a Taoist priest with a high cultivation realm. The term " heavenly master " came from the " governing by inaction " in the Tao Te Ching, which meant to achieve the realm of governing the country through inaction. Therefore, Taoist masters were usually regarded as the leaders of Taoism. A true person referred to a person who had achieved success in cultivation and possessed extraordinary ability and wisdom. In the Taoist tradition, Zhenren was regarded as the origin of all things in the world, an existence that surpassed humans. A true person usually did not refer to a specific person, but rather to a cultivation realm and state. In terms of appellation, Taoist Master and Zhenren could be considered to be higher than ordinary people. However, in the Daoist tradition, there were some higher-level titles such as Dao Ancestor, Dao Lord, Dao Zang, and True Master. These titles represented a higher cultivation realm and status. The answer to the question of which was higher or lower might vary according to the context and background. Generally speaking, Heavenly Master and Zhenren were relatively high-level titles in Daoism. Dao Ancestor, Dao Lord, Dao Zang, Zhenren Master, and so on represented higher cultivation realms and status. However, the specific situation still needed to be analyzed according to different context and background.
