Background: During the Renzong period of the Northern Song Dynasty (approximately the Qingli period), the border troubles (Xixia) were not resolved, and the internal "three redundancies" problem was serious. Fan Zhongyan was implementing the "Qingli New Deal", and the old and new party struggles were beginning to emerge.
Core idea: A modern sociology and agricultural school alumnus traveled through time and became a famous "prodigal son" in Bianjing. In order to hide his identity, he had to continue "living". When the civil and military officials of the Manchu Dynasty thought that he was eating, drinking, having fun, and sleeping in flowers and willows, he was actually using social survey methodology to reconstruct the tax system and border defense of the Song Dynasty.
