Song Dynasty. Emperor Shenzong: Qian Gongfu, Reminder in the Bureau of Policy Criticism, stated that upon encountering famine years and breaches of the Yellow River, permission should be granted to sell ordination certificates. / Emperor Gaozong decreed the sale of four-character master titles. / From the end of the Zhiping era, ordination certificates began to be sold. Formerly, they were made of yellow paper, and many were forged. At this time, Zhu Yi of the Ministry of Revenue memorialized, ordering that monks and Daoists use imperial brocade certificates. / Zhan Shuyi submitted a memorial requesting the cessation of the sale of ordination certificates. / Monks and Daoists were decreed for the first time to pay the exemption tax for corvée labor, called "peace and leisure money."
