Su Wan, a modern social animal, transforms into an ancient queen and discovers that officials have no pensions after becoming official, and their later years are desolate. She decided to establish a "official salary" system, withholding 3% from official salary, and the court would match another 5%, and receive it monthly after retirement. The emperor objected, believing that the treasury had no money. Su Wan used modern pension theory to persuade: basic pension insurance depends on social coordination, the younger generation supports the older generation, and the replacement rate must be reasonable, otherwise officials will only have to rely on northwest wind to retire. She engaged in verbal battles with ministers in the court, humorously popularizing concepts such as pay-as-you-go system, fund accumulation system, replacement rate, and social planning. In the end, the emperor was persuaded to pilot the "official pension", and Su Wan became the first empress in history to implement a pension system.
