What does the whole poem mean by "not as good as Wang Lun"?

The whole poem is "To Wang Lun", which is a farewell poem written by Li Bai, a great poet in the Tang Dynasty, to Wang Lun, a local friend, when he visited Taohuatan in Jingxian (now southern Anhui).

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.

Li Bai was about to leave when he got on the boat when he suddenly heard a farewell song from the shore.

Even if the Peach Blossom Lake reaches thousands of feet, it can't compare with Wang Lun's Farewell to Me.

Related background

Wang Lun, who lives by the Peach Blossom Lake, is good at poetry, writing and singing. He appreciates Li Bai's poems and songs very much. Every time I get Li Bai's poems, he always recites them day and night and never tires of reading them. He also knows that Li Bai, a poet, is good at drinking, and he is known as' One Hundred Poems of Li Bai Fighting for Wine'. So he makes wine with the best glutinous rice sorghum every year, which is stored underground and kept tightly. I hope that one day Li Bai can visit Taohuatan for entertainment. The local villagers laughed at his madness, but he never changed.

At that time, compared with Wang Lun, a villager, Li Bai was already a famous poet in China. Just like today's farmers and cultural celebrities, according to the level of communication, they belong to two different levels and cannot get together. However, Li Bai, who likes making friends all his life, is different. Anything that cannot cross the communication barrier is possible. This can be confirmed in his poems. When we open the Complete Works of Li Taibai, we can see that most of his poems are "sent" to this person and that person.
