Guan Gong belief belongs to traditional folk belief, which is a general term for various customs of folk belief in Guan Gong. It is a traditional belief culture. In 2008, Luoyang City applied for it and it has been identified as a national intangible cultural heritage by the State Council (Notice of the State Council on the Announcement of the Second Batch of National Intangible Cultural Heritage List and the First Batch of National Intangible Cultural Heritage Extension Project List 992X85), becoming a cultural treasure shared by all mankind. People respect and worship Guan Gong, which is actually a kind of spiritual sustenance and a beautiful vision of all Chinese people. This spirit and vision is gradually improved from abstraction, and it is concrete and perfect because of Guan Gong, and it is condensed and accumulated into a kind of belief culture: the loyalty, righteousness, benevolence, courage, courtesy, wisdom and trust that are condensed in Guan Yu and admired by all ages contain the ethics, morality and ideals of Chinese traditional culture, permeate the essence of human relations in Confucianism, and are the life values that converge with the teachings of Buddhism and Taoism. In essence, it is the moral soul of the Chinese nation that shines brightly and majestically.
