釋氏稽古略 3.56

3.56

In the bingchen year, the first year of Xianqing, in the fifth month, it was decreed that monks and nuns throughout the realm who violated state laws should be disciplined according to the monastic vinaya and must not be punished under the same statutes as the common people. In the eleventh month, the Heavenly Empress gave birth to a son, who was named Prince Foguang; this was Emperor Zhongzong. On the fifth day of the twelfth month, seven monks were ordained for Prince Foguang, and Dharma Master Xuanzang was requested to shave Prince Foguang's hair so that he might renounce the household life (from the Old History of the Book of Tang).
