Translation of sending a message to a friend

The original text and translation of Sending Friends is as follows:

Sending Friends, author: Li Bai.

Green mountains stretch across Beiguo, and white water surrounds Dongcheng.

This place is different, and I have traveled thousands of miles alone.

The thoughts of wandering in the floating clouds, the love of old friends in the setting sun.

I waved my hand and went away, the horse roared.

Translation:

Green hills lie on the north side of the city, and white water surrounds the east city.

Here we shake hands and say goodbye,

You are like a fluffy grass wandering thousands of miles on an expedition. A wanderer's thoughts are like clouds in the sky, and the afterglow of the setting sun is like a friendship that cannot be left behind. They waved goodbye frequently and left, and the horses neighed in farewell.
