The content of the whole poem is: the setting sun is far away, the weather is cold and the house is poor. Chai Men heard dogs barking and went home on a snowy night.
It's getting dark, Cangshan is getting farther and farther, the weather is cold, and the thatched cottage is poorer. I spent the night in this thatched cottage. Late at night, I heard a dog barking outside Chai Men. It was the host family who came back in the snow.
Traveling on snowy days is not a good job. When it was freezing, I was lucky to meet a place where I could avoid the snow. May you have friends and shelter in snowy days.
