It is said that the Chinese and Huns are in the same strain. After the demise of the Xia Dynasty in about16th century BC, a descendant of Gui Lu, Xia Hou, fled to the north, annexed other tribes and became the Huns, and the Huns were founded.
In the 3rd century BC, the Huns' ruling structure was divided into central Wang Ting, eastern left and western right, which controlled a vast area from the Caspian Sea to the Great Wall, including today's Mongolia, Russian Siberia, northern Central Asia and northeastern China.
In 460, Gaochang Beiliang was destroyed by Rouran. A small group of Huns who merged with Yuwen Xianbei tribe near Koguryo entered Liaodong Peninsula. Later, Yuwen usurped the Northern Zhou regime established by the Western Wei Dynasty. After that, Emperor Wendi usurped the Northern Zhou regime, established the Sui Dynasty and unified the Central Plains. During this period, the Huns also merged into various ethnic groups. Wu Luanhua and the Northern and Southern Dynasties became the last performance of Xiongnu on the historical stage of China.

In the middle of A.D. 1 century, Xiongnu, who was active in the Mongolian Plateau, was repeatedly defeated by the Eastern Han Dynasty in China and squeezed by the emerging Xianbei people in the Mongolian Plateau, and had to move westward. After 300 years, history books rarely mention the whereabouts of Xiongnu. In the 4th century A.D., this mysterious nation appeared in Europe and roamed the Don grassland on the northern shore of the Caspian Sea.
In 375 AD, the Huns began to expand on a large scale. They attacked the Danube to the west and destroyed the countries established by Alan and ostrogoths, conquered Armenia to the south and reached Persia and Syria. Huns are famous for their cruelty, and they often leave ruins and bones wherever they go. After the Huns invaded the Hungarian grassland, they settled down temporarily.
In 433 AD, Xiongnu Khan became the head of ministries in Attila and established a strong centralization. From the Volga River in the east, the Rhine River in the west and the Danube River in the south, a huge empire appeared. During Attila's 20-year reign, Buda, the capital of Xiongnu, became the political center of Europe, where envoys from various countries gathered to pay tribute and express their obedience. The Xiongnu Empire entered its heyday.
