Dr Peng Xin has seen and heard of Old Master Q many times. He and his wife are both vegetarians. When seeing a doctor, people often use Buddhist theory to enlighten each other, such as persuading people not to commit adultery. Dr. Peng Xin once said that the first time he saw his teacher, he was impressed by the temperament of the old mage. I stared at the old mage for a few minutes, and then in retrospect, I have never seen such a plump person in my life.
