Is Guan Gong a God or a Buddha?
Guan Yu is indeed a god. Some people say that Guan Yu is the reincarnation of Wu Quxing, while others say that Guan Yu is the reincarnation of Qinglong.
Guan Yu was crossed over by a monk after his death, so Guan Yu led the heavenly soldiers to split the mountain for 7 days and 7 nights to build a temple for the monk. Later, he was made a protector!
Next, I'll tell LZ about the Taoist position.
Guan Gong, also known as "Guan Sheng Di Jun" or "Guan Di" for short, was originally one of the four protectors of Taoism, and now Taoism mainly worships it as the god of wealth. As for its origin, it has been introduced before. Its function is not only to "cure diseases and eliminate disasters, exorcise evil spirits, punish treason and inspect companies", but also to "manage life, protect merchants and make money", and it is also called the God of Wealth because of its loyalty. Businessmen think there are three things. One is that Guan Gong was very good at financial management and accounting before his death. He once established a method of taking notes and invented a diary. There are four items in this calculation method: original, receipt, exit and deposit, which are very detailed and clear. Later businessmen were all recognized accounting experts, so they were regarded as business gods. Another way of saying this is that Guan Gong died because businessmen talked about business and traded with loyalty and credit. This belief was accepted by all walks of life in the Qing Dynasty, and its worship was particularly popular. In modern times, the brothers and green red gangs in Jianghu especially worshipped Guan Di, and sworn brothers in Jianghu also worshipped Guan Di, burned their watches and swore allegiance.
At present, Guan Yu has another title in Taiwan Province-Ling Xuan is higher than God.
In addition, some followers of Jainism or Taoism call Guan Yu "the 18th Jade Emperor", that is, the 18th generation of God's will. This statement is most prosperous in southern Fujian, and Taiwan Province Province has also inherited this statement.
