Later in 737, there was an incident in which the Yang Jun () the prefect of Yi Prefecture (夷州, roughly modern Zunyi, Guizhou), was accused of corruption and received a death sentence. Emperor Xuanzong commuted the sentence to caning for 60 times and exile to Gu Prefecture (古州, roughly modern Lạng Sơn Province, Vietnam). Pei submitted a petition, pointing out that while caning instead of death was grace already, public caning nevertheless was undignified for someone who had been an honored official. Emperor Xuanzong agreed and commuted the caning as well.
