Combined with the whole poem, talk about why Du Fu was worried.

The author began to write about the turmoil in the country, and the war made the people miserable, and then wrote his own sorrow through scenes such as "chaotic clouds", "dusk" and "sudden snow". Scene fusion. Then I wrote that I couldn't find a drop of wine in the bitter cold, the wine gourd had already been thrown away, and the glass was empty; There is no firewood, only an empty stove. Finally, I returned to my worries about the country. There is no news from several States, and I don't know what the situation is. I just need to sit down.

Pile up snow

Du Fu

Most of the people crying on the battlefield are the ghosts of the newly killed soldiers, only the old people who are sad to write poems. At dusk, suddenly snowflakes are dancing in the wind.

Abandoning the ladle is green, and the fire in the furnace is red. The news of the front-line battle and the news of his wife and sisters are unknown. Sadness sits in the air with his hands in the air.
