Who is the poet in Looking at the Moon and Thinking Far away? When was the poet? Is it a five-character poem?

(Tang) Zhang Jiuling

The moon, at this time is at sea, over the end of the world.

Bring a separated heart and long-term consideration at night.

Although I blew out the candles, it didn't get dark, and although I put on my coat, it didn't get warm.

So I left my message to the moon and then turned to my bed, hoping to have a dream.

The poet is Zhang Jiuling in the Tang Dynasty, a five-character poem!
