What weather is rendered by quoting ancient battlefield characters, and what is the purpose of the author's quotation?

The boundless wilderness, far from seeing people. The river bends like a belt, and countless peaks overlap in the distance. A gloomy and bleak scene: the cold wind roared, the sun was dim, the chrysanthemum was broken, the weeds withered, and it was as cold as a winter morning. Birds flew over and refused to fall, and stray beasts hurried by. The director of the museum told me: "This is an ancient battlefield, which was once completely annihilated. There are often ghosts crying and they will be heard every cloudy day. "

So sad! Is this the Qin Dynasty, the Han Dynasty, or something modern? It is said that during the Warring States period, both Qi and Wei recruited able-bodied men to serve, and Chu and Han also recruited soldiers to prepare for war. Soldiers ran to the frontier of Wan Li, exposed year after year, looking for grass in the desert in the morning and crossing the frozen river at night. I don't know where the way home is. Who do you confide in when your life is at stake? Since the Qin and Han Dynasties, there have been frequent wars in the four border areas, and the losses and destruction in the Central Plains are unprecedented in the world. In ancient times, it was said that Xia Xia, foreigners were not enemies of the emperor's army; Later, the education of rites and music was no longer promoted, and the military commanders used all the tricks of the Indiana Jones. Indiana Jones does not conform to benevolence, righteousness and morality, and Wang Dao is considered pedantic and unrealistic, and no one will implement it.

Oh, yo, yo! I imagined that the north wind shook the desert and Hu Bing took the opportunity to attack. The Lord is arrogant and underestimates the enemy, and the enemy soldiers rushed to fight at the camp gate. Various battle flags were erected on the Yuan Ye, and heavily armed soldiers were running in the valley. Strict military laws are frightening, officials have great power, and soldiers' lives are humble. Sharp arrows pierce the bones, and flying sand flies straight at people's faces. The enemy and our two armies fought fiercely, and the mountains and rivers were dizzy. The momentum is big enough to split the river, and lightning surges.

What's more, in the extreme winter, the air condenses, the world is blocked, the snow sinks into the calf, and the beard freezes. Birds of prey hide in their nests and rest, and warlike military horses linger. There was no heating in the cotton-padded clothes, so people were so cold that their fingers fell off and their skin cracked. In this bitter cold moment, under the disguise of Hu Bing's powerful hand, God came to chop and kill our soldiers, cut off the munitions halfway, and broke the ranks. A captain just surrendered and the general was killed again. The body died on the shore of Dagang, bleeding profusely in the cave under the Great Wall. Whether noble or humble, it has become a skeleton. This is endless pain! The drums are weak and the soldiers are exhausted; The arrow has been shot and the bowstring has been cut. White-edged hand-to-hand combat, the nod has been broken; The two armies are approaching, which is a matter of life and death. Surrender? Life will fall into a foreign race; Fighting, right? The bones will show gravel! The birds are silent, the mountains are silent, the night is long, the hate platform is flickering, the ghosts are condensed, the sky is dark, and the ghosts gather in clouds. The sun is bleak, reflecting the short grass, and the moonlight is bitter and covered with frost. Is there such a sad scene in the world?

I heard that Li Mu commanded the soldiers of Zhao, broke the invasion, opened thousands of miles of territory, and the Huns ran away. However, the Han Dynasty tried its best to fight the Huns, but the people were poor and weak. The key is to choose the right people, not the number of soldiers! Zhou dynasty expulsion? After that, the whole army returned to Beijing in triumph, held a sacrificial feast in the ancestral temple, and titled its achievements. Everyone is happy and comfortable. Between the monarch and the minister, they are dignified and kind, respectful and polite. The Qin Dynasty built the Great Wall, built fortresses to the seaside, killed countless people and dyed the land of Wan Li red and black with blood; The Han Dynasty sent troops to attack the Huns, although it occupied Yinshan Mountain, but the bones of the dead soldiers were everywhere, which was really not worth the loss.

Many people were born in heaven. Who has no parents? From childhood, I took the lead, held it and carried it, so as not to die young. Who doesn't have a brother? Who doesn't have a respectful wife? What benefits did they get when they were alive? What crime did you commit and get killed? Their life and death are unknown in China; Even if you hear someone accusing you, it's mixed. I was very sad and depressed all day and fell asleep at night. As a last resort, we had to display sacrifices, drink alcohol to pay homage, look from a distance and cry bitterly. Heaven and earth are sad for it, and plants are also sad. Such a gloomy condolence sacrifice cannot be perceived by the souls of the dead in heaven, and their souls have no refuge. Besides, there will be famine after the war and people will inevitably be displaced. Alas, alas! Is this caused by the times or by fate? This has been the case since ancient times! How can we avoid war? Only by preaching enlightenment and practicing benevolence and righteousness can the four clans defend the territory for the emperor.

The boundless wilderness, far from seeing people. The river bends like a belt, and countless peaks crisscross in the distance. A gloomy and bleak scene: the cold wind roared, the sun was dim, the chrysanthemum was broken, the weeds withered, and it was as cold as a winter morning. Birds flew over and refused to fall, and stray beasts hurried by. The director of the museum told me: "This is an ancient battlefield, which was once completely annihilated. There are often ghosts crying and they will be heard every cloudy day. " So sad! Is this the Qin Dynasty, the Han Dynasty, or something modern?
