In the poem, "people go home at night in a snowstorm" should be interpreted as "the master works hard outside and goes home at night" Because the first sentence "Chai Men smells dogs barking" and "Chai Men" should be written about the movement in the hospital heard in the dark and on the couch. The phrase "snow" should not be seen, but heard, because I heard all kinds of voices and knew that someone was returning in the snow.
The last two poems, "Chai Men smells dogs barking, and the snow returns to people at night", were written after spending the night in the mountain. In terms of words, "Chai Men" is connected with "White House", "snow" is connected with "cold" and "night" is connected with "sunset". In this way, from the perspective of the whole poem, although the second half of the poem has opened up another poetic realm, it is closely connected with the first half.
But here, the cause has made a leap. It seems that "smelling dogs barking" is at night, and most travelers who are tired of hiking have already slept; There is a period between dusk and night, from the invasion of cold current to the exchange of snow, from entering the hut to going to bed, which should be described, but the pen skips this period and omits some plots, making the poem more refined and compact.
The poet thought carefully between his choices. If this effort is not made, perhaps the second half of the poem should further describe the depression of people living in houses, write about the desolation of mountain houses and the silence of the environment, or write about the coming of snow at night. Otherwise, you can also write about your own travel and your thoughts after staying overnight. But the poet put these things aside and didn't write. Unexpectedly, he saw a noisy dog barking in the silence. This shows the change of scale, giving people the feeling that a strange peak suddenly appeared on the flat ground.
