What role does the description of "winter" night scene in Zhu Ziqing's prose play?

1. A close-up of three winters, shaken out with changing lenses, forms a unique set of different landscapes in winter, and has a unique charm. The first picture: father and son sit together and eat hot boiled tofu. The second picture: "I" and my friends are boating on the West Lake. The third picture: Empty Mountain Canyon-Taizhou.

2. As soon as I served, I looked at the pot eagerly, waiting for the hot air, waiting for the tofu that fell from my father's chopsticks in the hot air.

The wind is a little strong, and the moonlight sheds soft water waves; Just then, the line reflected light, like new silver. There are only faint shadows left on the mountains on the lake.

Although it is always winter outside, it is always spring at home. Once I went to the street, when I came back, the wide window of the kitchen downstairs was open, and their mother and son were lined up side by side; Three faces smiled at me with innocent smiles.

3. Black aluminum pot, snow-white tofu and orange lights will suddenly expand the visual image in space, suggesting the time and space of past lives. Who hasn't had this past? Around the fire, the family ate boiled yam and sweet potato, and let the whistling north wind blow the window lattice. The memory of this moment becomes so clear that it suddenly evokes a poetic tenderness.

(1) brings warmth to the frozen night.

(2) The affection between father and son, the love between father and son is infinitely extended by this enlarged close-up.
