The envoy Ruan Jing-zhen and other who had been sent by Hu Di of Annam, accompanied the Messenger Nie Cong, came to Court and submitted a memorial as follows: "I have humbly received the Imperial letter, instructing me to display sincerity. If I transgress against Heaven and Earth, dare to be double-minded or have doubts and become disaffected, may the gods strike me dead! Now I am sending the attendant minister Ruan Jing-zhen and others to offer felicitations on the coming New Year's Day, and to receive and bring back Tian-ping. I will lead the people of the country to receive him at the border." The Messenger Nie Cong and the others spoke enthusiastically about Di's sincere heart and respect for orders. The Emperor thus approved this.
