Late-night memories

Author: Lu Chen

Moonlight flows into the threshold?

I thought it was sunshine?

Open the door or late at night?

Soon, a wind blew from the north?

As if blowing the bowstring of the moon?

So I heard the sound of dawn?

The river bank was crushed by the shadow of the mountain?

There are stars flowing through the wilderness?

Feeling that everything is still asleep?

Only I was the first person to wake up.
