Mountain fog
Mountain fog, like a naughty child,
Running in the valley in the morning.
After a while, I ran from the mountain to the mountain.
Then it permeates the mid-level air.
It's chasing frolicking friends,
Or hide the cat in the green forest?
The sun is out, smiling face,
Tired of running in the fog, I settled down in the mountains.
Look, the string of crystal dew on the green leaves,
It is its flowing sweat that shines in the sun.
It climbed into the grass,
Then playfully holding Little Red Riding Hood.
