Around 3000 BC, primitive tribes on the land of China were already very prosperous. They either merge with each other due to intermarriage, or fight each other due to competition for the living area. Slowly, some stronger tribes annexed weaker tribes, and some large tribal groups formed.
At that time, two powerful tribes formed on the Central Plains of the Yellow River Basin. One of their leaders is Emperor Yan of Shennong, and the other is Huang Emperor of Xuanyuan. It is said that both of them were born after marriage between the Shaodian tribe and the Yous tribe, so they are still close relatives. At the beginning, Emperor Yan's tribe was in the Jiangshui Valley, while Emperor Huang was in the Jishui Valley. Later, Emperor Yan led the tribe to expand to the Central Plains of the Yellow River, and led the tribe to transition from a safaris life to a farming life; at this time, the Yellow Emperor also migrated to the Central Plains. They came to Zhuolu, the site of Emperor Yan, and wanted to settle down here.
In order to compete for land and resources, the two tribes finally fought regardless of family affection. They fought three battles in Banquan, southeast of Zhuolu. In the first two battles, because Emperor Yan had a large number of people and attacked with fire, he defeated the Yellow Emperor. However, in the third battle, Huangdi contacted many tribes in the northwest with him, and dealt with Yandi together; and when he was fighting, heavy rain fell again, which made Yandi’s fire attack lose its power. Therefore, Yandi Defeated and captured. However, Huangdi thought of family affection and did not kill Yandi. Instead, he still made him the leader of his own tribe and only allowed him to move to the south.
Immediately afterwards, Huang Di expelled the meat porridge who did not listen to his orders from the Central Plains. So the Yellow Emperor became the leader of the tribal alliance on the Central Plains. The unification and integration of tribes promoted the development of production and culture. Huangdi not only allowed his tribe to settle down in Zhuolu, but also encouraged all tribes, including his own tribe, to promote Yandi’s agricultural farming techniques and methods of treating diseases with herbs. At the same time, it is said that he also let his wife Leizu teach people to raise silkworms. Reeling silk, woven into silk and silk to make clothes; let Cangjie summarize the note symbols used in practice and create words; also ordered Fengning to make pottery, Yongfu to make mortar and pound rice, Gonggu and Huodi to make boats; Ming Rongcheng formulated the calendar, Xihe inferred bad luck, and Linglun made musical instruments.
At this time, another tribe became stronger and stronger. Its name is Jiuli tribe. The leader of the Jiuli tribe is Chi You. It is said that this tribe is composed of their ninety-nine-eighty-one brother tribes'. Although they were still hunting mainly at this time, they had learned copper smelting techniques. They already know how to use copper spears and broadswords, and their weapons are very sophisticated. The Jiuli tribe was originally a tribe under the control of Emperor Guiyan. After Emperor Yan was defeated, they were banished to the eastern part of the Central Plains, in the eastern part of today's Anhui, Henan, and Shandong as far as the coastal area. Seeing that his own strength could compete with the Yellow Emperor, Chi You went to contact the Emperor Yan, and prepared to join forces to retake the Central Plains. However, Emperor Yan saw that the Huangdi ruled the tribes of the Central Plains very well, so he did not want the people to suffer from the war anymore, so he refused to participate. As a result, Chi You contacted the Miao people in the south and marched toward the Central Plains.
Chi You's army is brave and powerful. Legend has it that they are all bronze-headed and iron-arms, invulnerable to swords and guns; they will also call the wind and rain, bringing the mist and poisonous mist in the southern mountains and forests to attack the enemy together. Chi You's army was like a broken bamboo at the beginning, until it reached the Huangdi's lair, Zhuolu.
At this time, the Yellow Emperor gathered reinforcements from various tribes loyal to him and assembled near Zhuolu. At the same time, he summoned his subordinates to carefully study the characteristics of Chi You's army and the methods of destroying the enemy. The decisive battle began. Chi You's army attacked fiercely and set aside the poisonous fog array. For a while, the battlefield was dark, clouded, flying sand and rocks, making people dizzy. Huangdi immediately ordered the launch of the guide car, allowing his army to rush out of the poisonous fog under the guidance of the guide car and counterattack the enemy. Seeing that the poisonous fog array was broken, Chi You sent out his special army—the soldiers screamed and killed one by one with bull-headed horse-faced faces, green-faced fangs, copper-headed iron arms, and hideous faces. When the Emperor Huang saw him, he ordered the release of a large number of tigers, leopards, bears, and other beasts that he had already trained. These beasts met Chi You's soldiers dressed as wild beasts, thinking they had seen the weaker of their kind, they rushed to bite them. No matter how fierce the soldiers were, they couldn't stand the bite and attack of the beasts. One by one, they were so scared that they fleeed with their heads in their arms. The front team of Chi You's army was defeated, and the main force of the Yellow Emperor pressed forward. Chi You's army couldn't resist it, and they retreated one after another. Chi You was captured by Huangdi's army when he fled to central Jizhou. Huangdi ordered his head to be cut off.
Huangdi defeated Chi You, and then defeated Kuafu and Xingtian, who refused to listen to his orders and tried to compete with him for the leadership of the tribal alliance. From then on, he firmly grasped the rule of the Central Plains.
Since Emperor Yan not only refused to participate in Chi You's rebellion, but also worked hard for the people until he was old, the Yellow Emperor was very moved. He felt that his handling of Yan Emperor in the past was too much. Therefore, he ordered the Emperor Yan and his tribe to be brought back to the Central Plains to live with his tribe. In this way, the two tribes of Yan and Huang lived in harmony, merged with each other, worked together and multiplied in the Central Plains. They became the ancestors of the Chinese nation.
