The story begins around the time when the glory of the prosperous Tang Dynasty has not yet been extinguished, like a perfect full moon hanging in the sky; the inner sea of Kyushu is clear, and singing and dancing are flourishing.
In Yangzhou City, the streets are bustling with people, and the whole city is decorated with lights and colorful lights, filled with the joy of the end of the year. In the corner of the adjacent shop, there was a tattered mat, and sitting on it was a skinny beggar. His cheekbones were protruding, and his eyes looked extraordinarily large due to hunger. He held his bony knees with both hands, shivering in the north wind and huddled up. A gust of fragrant wind drifted by, and a group of men and women in exquisite clothes and belts surrounded a little girl wearing mink fur and pink carvings. They passed by him holding a fish-shaped paper lantern. The little girl lost her temper and threw the paper lantern aside with a pout and a frown.
The beggar was so hungry that he couldn't help but pick it up and take a bite of the fish painted on the paper. The wax oil from the lamp dripped onto his hand and burned the small fish painted on the paper. The beggar stared blankly at the ashes, and tears suddenly fell down.
The little girl was startled, perhaps because the sadness in his eyes was too deep, so she took him back to Changgemen and became her junior brother who would stick to her like a little tail in the future.
The snow in the north of Saibei fell like goose feathers, covering the gunpowder smoke and blood silently below. A group of soldiers wearing black armor had just experienced a fierce battle. A soldier wiped the blood on his face and found a crooked tent next to the ruins. He held his breath and used a mo knife to open the fur in front of the tent. Felt, gestured to the soldiers behind him, and rushed into the tent first: there was a woman dressed as a foreigner in the tent. She screamed at the soldiers, pulled the unkempt little boy next to her, and strangled his neck. The woman looked up at him with tearful eyes, full of vital prayers.
The child's limbs twitched helplessly, and his face turned purple due to lack of oxygen. The soldier roared angrily, tore the woman away from the child and threw him aside. He picked up the dying child on the ground, put it into his cold arms, and carefully wrapped it in felt.
The soldier took the boy with him and watched him grow up, but on a snowy night, he quietly ended his life. The boy put on his cold armor and became the iron and copper wall standing at Yanmen Pass.
