From which poem does "Emei Mountain draws the river flat in half moon and autumn" come? Who is the author?

From Li Bai's "Emei Mountain Moon Song".

The original text is as follows:

Li Bai, Emei Mountain Moon Song

Emei Mountain is half moon and autumn,

Shadow into the Pingqiang River.

At night, Qingxi flows to the Three Gorges.

Yuzhou can't see you.

Appreciate:

On a crisp autumn night with bright moonlight, the poet went down the river from Qingxi Post in a boat. The moon reflected on the river, like a good friend, accompanied the poet. But in the journey from Qingxi to Yuzhou, the moon is always blocked by mountains on both sides, which makes the poet miss him very much.

Translation:

In front of the steep Mount Emei, there is a half-moon suspension. The flowing Pingqiang River reflects the moon.

Set out by boat at night, leave Qingxi and go straight to the Three Gorges. Miss you, hard to meet, reluctant to part with Yuzhou.
