Tracing back to the origin of Mongolians, we can start with the name Shiwei, which was discovered in Wei Shunian and belongs to Shiwei tribe of the same language family as Xianbei and Qidan. The name Mongolia first appeared in the Biography of the Northern Emperor Wei Shi in the old Tang Dynasty, which recorded a Mongolian Shiwei of Shiwei tribe. Wumeng is a transliteration of Mongolian in Tang Dynasty. Today, the activities of various ministries in Shiwei start from Taoer River in the south, Hulun Lake in the west, Nenjiang River in the east and Heilongjiang in the north. As far as Mengwu River is concerned, it should be near Ergong in the north of Daxing 'anling. In the Song, Liao and Jin Dynasties, different translations of Mongolian, Mongolian and Mongolian Li began to appear in China's historical records. During the People's Republic of China (PRC) period after the founding of the People's Republic of China, Jin used the translated names of Mongolian when he helped to write Chinese documents in his works. Since then, the name has been uniformly used by Mongols. However, the history of nomadic origin is always full of legends. The story about the origin of Mongols in the Secret History of the Yuan Dynasty goes like this: Canglang, born of fate, named Kyle Tiechinar, fell in love with a white doe named Hoemalanle and paired with it. Together, they crossed Tengger Haizi, came to Bourhan Mountain at the source of Wonan River, and gave birth to a man named Bata Chihan. Of course, it is impossible to combine with a wolf and a deer to make a man. However, this legend reflects the totem culture in primitive civilization. From 10 century to 12 century, the Mongolian Plateau was ruled by Liao and Jin successively. Gradually, they migrated to the west and came into contact with the Turkic tribes who settled on the Mongolian grassland, and changed from primitive hunting ethnic groups to nomadic ethnic groups. However, the rather primitive clan system still maintains the form of social organization, which has great constraints and influences on all aspects of their society. In the form of family organization, a man can marry as many wives as he can support. The status of the first wife is the highest among many wives. In addition, the original custom of father marrying mother and brother marrying sister-in-law still exists. A man can marry a sister, and a sister can marry a father and son. In this way, the Mongols formed their clan tribes according to their blood relationship. /kloc-There were Tatar tribe, Taichiwu tribe, Kelie tribe, Naiman tribe and Meyer begging tribe in the 0/2nd century. /kloc-In the late 20th century, the primitive collective nomadism was gradually replaced by individual nomadism. The accumulation of private property led to the polarization between the rich and the poor, and a prominent family was born among Mongolian clan members, with Yan Na as its representative. Yan people have their own soldiers, named Nakel. Chloe worked and fought for Yan State, which provided them with food and clothes, and distributed the goods and people and animals captured in the war to them as trophies. Therefore, in the 12 century, the Mongolians on the grassland not only retained a considerable part of the primitive clan system, but also established simple slavery. It should be pointed out that during the formation of Mongolian tribes, Genghis Khan's position and role in Yan Na was very high, which was different from that after the establishment of the Mongolian Empire. During the Mongol Empire, Yan Na also belonged to the ruling class, but there was a strict identity difference with princes, that is, monarch, servant and servant. Khan is the head of all Genghis Khan families. Although Yan Nami's national identity is still hereditary, it has changed in essence. They changed from nobles or tribal leaders to subordinates of Genghis Khan, and their status could not be compared with the descendants of their master Genghis Khan. /kloc-in the 0/2nd century, due to the influence of the policy of Jin State's division, Mongolian ministries on the grassland continued to kill and plunder each other in an extinct way for pasture and population. The descendants of Genghis Khan, who unified the Mongolian grassland in history and established the Great Mongolian Empire, came from between the Enen River and the Kulun River in the northeast of outer Mongolia today and belonged to the Qiyan tribe of the Jinji nationality in Borziji Prefecture. According to records in the Yuan Dynasty, the 10 ancestor of Genghis Khan, that is, the 10 descendant of Canglang in his previous legend, was called Buduni. His mother, Allen Guo Pin, has given birth to two sons. After her husband's death, on a magical night, Arangu saw a god man come to her bed in his sleep, and gave birth to a son named Duan Boyi the next day. After Allen; The death of

Later, with the help of Tousard, the second brother, he led the clan to subdue a group of herdsmen who migrated from aquatic plants and developed from then on. Interestingly, there is also a legend about the origin of Mongols in Historical Records. According to the book, the ancient Mongolian tribes were slaughtered in the war with other tribes, leaving only two men and two women, namely Nie Gusi and Qi Yan. They fled to Kunshan, Ergon, now Daxing 'anling, where they lived and multiplied for a long time, and their descendants gradually formed a clan. Therefore, all Mongolian tribes originated from the primitive clan of Gu Ni Temple and Qiyan. Like the first legend, the historical collection also mentioned the legendary woman Alain's fire. Buduni, like Yuan, is the ancestor of Genghis Khan. Anyway, this man should have existed, and the history of this family from him to the rise of Genghis Khan is long and tortuous.
