Romantic feelings in ancient poems (need a little appreciation and annotation)

The snow is dark and the flag is painted, and the wind is ringing.

When you wrote about joining the army, "Zhang Ya" only "retired the phoenix" and "warrior" had "circled the Dragon City". The words are magnificent, dual, but consistent, and the military actions against aggression are written quickly and forcefully, and the fierce battles are set off in the snow of the battlefield.

In the world of April, the flowers have withered, and the peach blossoms in the ancient temples have just bloomed.

In April of the lunar calendar, spring goes to summer, and the flowers outside the mountain have withered, while the peach blossoms at Dalin Temple on the top of the mountain are in full bloom.

It's late at night until it snows heavily, because you can hear the sound of bamboo branches breaking from time to time.

That is to say, lying in bed at night suddenly feels a little cold, and then I see the window shining. It turned out to be snowing. I always hear the sound of bamboo being crushed and know that it is snowing heavily. When I feel the cold window is bright, I know that there is snow, I smell the sound of bamboo, I know the weight of snow, and my writing is tortuous, ingenious and unique. Writing scenery also contains feelings in scenery. Snow on a Cold Night and the Sound of Folding Bamboo euphemistically convey the poet's loneliness and infinite feelings after being relegated.

When the moon comes out, the birds are startled, and the sound enters the spring stream.

In this spring mountain, everything is intoxicated with the color and tranquility of the night. Therefore, when the moon rises, bringing bright Yin Hui to this empty valley shrouded in darkness, all the birds in the mountain are startled. Birds are surprised, of course, because they are used to the silence of the valley. It seems that even the moon rises with new excitement. But it is also conceivable that the bright moonlight makes the scene before and after the valley suddenly change.
