Wang Bo, the "four outstanding figures in the early Tang Dynasty", was exiled for offending Tang Gaozong in the novel Ying Feng Wang. He went to Jiao Jiao to visit his father and passed through Hongzhou, which coincided with the Double Ninth Festival. Taizhouyan of Hongzhou gave a banquet to entertain the guests and amused himself with poetry. Wang Bo improvised Preface to Wang Tengting: "There is a treasure of things, a city where dragons shoot cows, outstanding people, and Xu Ru got out of the bed of Chen Fan."
