Once when he accompanied Wenzong to Weiyang Palace, as soon as the car stopped, Wenzong ordered him to praise it in dozens of words. Everyone is amazed by his ability to speak clearly, to speak both ways, and to speak fluently and gracefully. Wenzong smiled again and said: "You will recite three more poems praising peace."
