The two of them hit it off instantly, and they were on a boat on the river, singing wine while boating, and chatting about their interactions in the literary world. Before leaving, Wang Changling wrote a poem "Baling Farewell to Li Twelve" as a gift to Li Bai: "As the Baling Island is swaying to Zhufen, the rumors of the Qingjiang River are heard. The mountains are long and the autumn city color is not visible, and the water clouds are in the sky at dusk."

Li Bai also never forgot Wang Changling's friendship. Later, I heard that Wang Changling had been demoted to Long Biaowei, so he wrote a poem and sent it to comfort him. Li Bai's poem "I heard that Wang Changling moved to the left and Longbiao was far away and sent this message": "The poplar flowers have fallen and the son is crying, and I heard that Longbiao has passed the five streams. I send my sorrowful heart to the bright moon, and follow the wind until the night is west.
