In the summer of April of TaBaLiWei's thirty-ninth year, all ministers and adults came to offer sacrifices to Le Sheng, but only adults with a hundred steps could not hesitate. Mr. Bai is Murong Xianbei. Mr. Murong's skin is white, and he is called "white and Xianbei". TaBaLiWei killed Lord Bai. Killing the Lord is respectful from far to near, and all are shocked. Bai Gong was killed, which proved that the established Tuoba State had a powerful repressive force. Bartoli Liwei made a declaration in Le Sheng and told the adults: "My previous generation has been to Xiongnu and Taton, and I was greedy for money and plundered the border people. Although I have gained something, their casualties are not enough to make up for it, and recruiting more enemies is not a long-term solution. " This is not only Tuo Ba Liwei's declaration to the adults of various ministries, but also the announced strategy for establishing the country. So Tuoba was friendly with Wei and Jin Dynasties. After Tuoba Liwei moved to Lesheng, there were four big tribes and many small tribes, totaling 108 big, medium and small tribes. The four major departments are Xianbei Tuoba Department, Xianbei Deerless Hui Department, Xianbei White Department and Wuwan Department (Wuhuan and Northern Hu People). Tadun was the 50,000 king in the last years of the Eastern Han Dynasty. King Wu Wan under the command of Le Sheng is Kuxian. According to the command of Tuoba Department, Tuoba Liwei obtained the hereditary position of Grand Chief, and was the leader of this tribal alliance, commanding the whole desert south. After Tuoba GUI ascended the throne, he was honored as the ancestor.

After the death of Sima Yan, Emperor Wu of Jin Dynasty, the "Eight Kings Rebellion" intensified. Tuoba Xianbei, divided into three parts, opened up Xinjiang and prospered the country, respectively expanding the sphere of influence of his tribe, which was called the Huanmu period at that time. During this period, Liu Yuan, a descendant of Xiongnu, became king, established the Han State, and began the period of two Jin Dynasties and sixteen States. In order to fight against the Han State, the Western Jin Dynasty formed a military alliance with Tuoba Yi and Tuoba Luyi. Then, Tuoba Louis unified the three departments and acquired the territory of five counties north of Yanmen in the Western Jin Dynasty. The court of the Western Jin Dynasty successively appointed Jin as Khan, Daigong and Daiwang. Xiong Lu takes Lesheng as the northern capital, the old Pingcheng as the southern capital, and the northern Xinjiang is famous. "Shu Wei Jixu Moody" records: "In six years, Cheng Shengle thought the northern capital and Pingcheng thought the southern capital." In six years, that is, in 3 13, the first year of Emperor Jianxing of Jin Dynasty, Lesheng has been the capital of Tuoba Xianbei for 55 years. In 3 15, Louis established Daiguo in Lesheng. In April 386 AD, Tuoba GUI, the grandson and acting king of Tuoba GUI, established the Northern Wei Dynasty, making its capital Lesheng, and called it Wang Wei. At that time, the crops planted in Daiguo were mainly millet. Because millet can process fried rice, which is the most convenient food for northerners. Millet grass, commonly known as Mimi, is an excellent forage. In 367 AD, Yan Qian's army attacked Chile. After the country was changed, the army trampled on Tian Mi, and Tuoba Shiyi angered them, which eventually led to a great war. "The Second Year of Zijian Haixi Taihe" records: "In the early days, Li (former Mu Rongchui) crossed the land, violated his Jitian, and took his anger out on Tuoba Shiyi, the acting king. Yan Pingbei's general Wu led his troops to guard the clouds from Youzhou. In August, Tuoba Shiyi attacked the cloud and abandoned the city. General Zhenwu is eager for He Yuxin to fight. " Tuoba Shiyi defeated Yan Qian's army. After Tuoba GUI's death, posthumous title, Emperor Daowu of the Northern Wei Dynasty. In 398 AD, Tuoba GUI proclaimed himself emperor, opened the feudal monarchy, and the Northern Wei Dynasty reached its peak. Since the reign of Tuoba Liwei Le Sheng, 15 leaders of Tuoba Department have acceded to the throne here. In addition, among the seven generations of kings, six have LeSheng as their capital. Since Tuoba established Lesheng as its capital, Tuoba Yao Lu, Tuoba Guihuai and Tuoba XI have built Lesheng New Town on 3 13, 337 and 34 1 3 respectively. In the autumn of 398 AD, Wang Wei's Tuoba GUI ascended the throne and proclaimed himself emperor, and the emperor set up a banner. At this time, Le Sheng was not only the capital of adults, Khan and emperors in the West, but also the imperial capital of the Northern Wei Dynasty. Le Sheng became a veritable hometown of emperors. Tuoba GUI spread all over Yinshan Mountain, desert and things, and conquered all directions. The northern territory was restored to the command of the adults in the west. The southern foot of Yinshan Mountain occupied Henan land, south of the Yellow River in Hetao, and recovered the land ceded by the Western Jin Dynasty during the Huanmu period and the land north of Ku Ling. Tuoba GUI conquered Kumoxi, Jeru, Gaoche, Xiongnu Biebu, Rouran and other tribes, and gained a large population. In the past, many rebellious tribes also joined in. By 398 AD, the population of the Northern Wei Dynasty had reached 2 million.
