The first two sentences are documentary, with "homesickness" written on the side. The first sentence "moderate hospitality" has taken root in "homesickness". In the Tang Dynasty, on the solstice of winter, people should celebrate with their relatives at home. But now the author meets this festival in Handan Inn, and I don't know what to do. The second sentence is about the writer's holiday in Handan Inn. The word "tuck" vividly describes a sitting posture.
The word "in front of the lamp" not only dyes the environment, but also points "night" to show "shadow". A word "companion" connects "body" with "shadow" and gives "shadow" human feelings. Only the shadow of kneeling is accompanied by the kneeling body. The author's loneliness and homesickness are beyond words.
The last two sentences use imagination to write "homesickness" on the front. In the last two sentences, I changed my tune, instead of writing directly about how I miss home, I imagined my family sitting around the lamp at night from the winter solstice, talking about myself as a long-distance traveler, so as to show my homesickness and make it more real and touching.
What is touching is that the scene he imagined when he was homesick was the family's yearning for himself. This winter solstice, my family must be very unhappy because I am far from home. When I put my knees in front of the lamp and miss my family until late at night, my family is still awake and sitting in front of the lamp, "talking about travelers."
The author didn't specify what he "said", which left a broad imagination space for readers. Everyone who has enjoyed family happiness and had similar experiences can think a lot according to their own life experiences. The author didn't use flowery words or play with too many artistic skills, but used plain and simple language to express homesickness incisively and vividly.
