"Li Bai was about to sail, but suddenly he heard singing on the shore" comes from the first sentence or two of Li Bai's ancient poem "To Wang Lun" in the Tang Dynasty. The whole poem is as follows:

Li Bai was just about to leave when he heard a farewell song from the shore.

Even if the Peach Blossom Pond is deep, it is not as deep as Wang Lun's sending away my love.

To annotate ...

(1) Percussion song: a folk singing form. When singing, you can beat the time with your feet and sing while walking.

② Taohuatan: It is one hundred miles southwest of Jingxian County, Anhui Province. The unified yearbook calls it unfathomable.

③ Deep thousands of feet: The poet compared the friendship between Wang Lun and him to a pool of clear water and a deep thousands of feet, and wrote a profound friendship with exaggerated methods (neither a pool of clear water nor a deep thousands of feet is real), which was very touching.

4 not as good as: not as good as.

⑤ Wang Lun: Li Bai's friend. When Li Bai visited Taohuatan in Qiongxian County (now Anhui Province), Wang Lun from nearby Jia Cun often entertained Li Bai with his own wine, and they formed a deep friendship.
