The setting sun is far away, the weather is cold and the house is poor. Chai Men hears dogs barking and returns on a snowy night. The meaning of this poem is: at dusk, the mountains are boundless and the road is long. When it's cold, the thatched cottage looks poorer. Suddenly the dog barked outside Chai Men, and the family who stayed at home on a snowy night came back.
Open the door in the morning, the mountains are covered with snow, the snow eyes are pale and the sun is cold. It means that when you open the door in the morning, you will see the snow all over the mountain. After the snow, the white clouds were pale and clear, and even the sun became cold.
