What is the poem in front of Singing on the Shore?

Suddenly I heard the song on the shore, which is a line in Li Bai's poem To Wang Lun. The whole poem is as follows:

A gift for Wang Lun.

Tang Libai

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.

"Tapping songs" is a form of singing and dancing, that is, singing while stepping. It can also be simply understood as singing.
