 After the Hubu Guanpiao it was only rarely suggested by court officials to reintroduce paper money to the Qing Empire, among these were Cai Zhiding (蔡之定) in 1814 and Wang Yide (王懿德) in his treatise on money known as "Qianbi Chuyan" (錢幣芻言).Peng Xinwei suggested that the Manchu rulers of the Qing were very much atavistic towards the inflationary pressure that the earlier Jurchen Empire experienced after they had abused their ability to print Jiaochao banknotes.Modern scholars argue that the banknotes issued during the Shunzhi period, while only brief, likely entrenched the reluctance of the Qing dynasty to issue banknotes because this issue also proved inflationary confirming their fears.
