"He knows that the dew will be frost tonight, and how bright the moonlight is at home!" Why does this poem miss the feelings between brothers the most?

The first sentence of this poem, "A wanderer listens to the drums to herald a war", points out the heavily guarded and deserted appearance of "late at night" and "wartime" at the beginning. "Autumn" and "the sound of geese" in the second sentence further illustrate the season and place where he misses his brothers and sisters. It was autumn, flowers and trees began to wither, I was at the border, and the sad cry of lonely geese made people feel empty and lonely.

Du Fu is describing his feelings of missing his brother. Because of the war, he and his brothers were scattered in different places; The "homeless" in the sixth sentence is even more sad, because he was not only separated from his relatives, but even his hometown was destroyed by the war.

In the last two sentences, he described the feeling that he didn't receive a letter from home because of the war and was very worried about everyone's safety. Especially the word "no truce" in the eighth sentence can echo the first sentence, and the whole poem is very complete in emotional expression.

This poem was written by Du Fu in Qin Zhou in the autumn of the second year of Gan Yuan (759). In September this year, Shi Siming led the troops south from Fan Yang, captured Bianzhou and moved west to Luoyang. Shandong and Henan are at war.

At that time, Du Fu's younger brothers were scattered in this area, and because of the war, there was no communication, which made him feel intense anxiety and yearning.

Remembering Brothers on a Moonlit Night is a true record of his thoughts and feelings at that time. Homesickness for relatives and friends is a common theme in classical poetry. In order to avoid mediocrity and originality, it is not enough to rely solely on the author's life experience, but also to be ingenious in expression. It is in dealing with this common theme that Du Fu reveals his true colors.

The above four sentences are written casually, which seems to have nothing to do with missing my brother, but they are not. Not only writing "Looking Back at the Moon", but also listening to drums, geese and cold dew make the author feel sad and nostalgic. In fact, I remember every word of my brother, and every word is affectionate.
