At the end of the Xu Dynasty, the imperial court imposed heavy taxes and people everywhere were in dire straits. Zhang Jiuchong rose up, overthrew the old dynasty, established Da'an, promoted the Dharma under his reign, advocated the rule of law, and issued an order to the world: the emperor who violates the law is guilty of the same crime as the common people. Yuan Wen, the magistrate of Fengping County, investigated the case of King Ji who tortured and killed people for fun, and appealed to the capital. Unexpectedly, the emperor protected King Ji, and then he realized that the person who made the rules did not follow the rules, but the people under the rules took them as a matter of course. From then on, he abandoned his official position and embarked on the path of spiritual practice, becoming a person who does not follow the rules.
