What's the story of Eastern Wei and Western Wei?

? Gao Huan became the Prime Minister of the Northern Wei Dynasty, with great power and heavy troops in his hand. The filial emperor Xiu Yuan was very afraid of him. In May 543, Xiu Yuan wanted to crusade against Gao Huan in Jinyang, so he lied about crusade against Nanliang and ordered the army to impose martial law. In June, Xiu Yuan sent a secret letter to Gao Huan, saying that he knew that Yu Wentai and He Basheng of China attempted to rebel. So he pretended to go south and wanted to send troops to conquer them. He hoped that Gao Huan would send troops to support him, while Xiu Yuan wanted to test Gao Huan. Gao Huan replied, "People have been sent to lead an army." . Gao Huan is a clever man. Xiu Yuan knew that Gao Huan knew about his plot, so he took out the letter of Gao Huan and asked his ministers to discuss countermeasures.

? At this time, Gao Huan also called his men to discuss, and then went to the table and said, "I have been alienated by the traitors around your majesty, and I know that your majesty has concerns and doubts about me. If I dare to disappoint your majesty, I will be cursed, childless. If your majesty believes that I am sincere, so I don't have to use the army, please depose the traitor around me. " This letter has been exchanged several times, but no understanding has been reached. Wang Sizheng, general of Zhong Jun, persuaded Xiu Yuan: "Gao Huan's intention is obvious, and everyone can see it. This place is not suitable for fighting. Yu Wentai is facing the royal family. How can it not be successful to move to him now and recover the old money later? "

? Xiu Yuan sent Liu Qing, assistant minister of Sanshui, to Gaoping to meet Yu Wentai to discuss the current situation. Yu Wentai asked to meet with Xiu Yuan and Liu Qing to report back to Beijing. Xiu Yuan asked Liu Qing privately, "Do you have any good suggestions?" Liu Qing said: "Guanzhong has a favorable terrain. Yu Wentai's talent and strategy are worth relying on. Jingzhou is not a crucial place, and it is close to the strong enemy beam in the south, so you can't go. " Xiu Yuan also asked Yu Wenxian, the cabinet governor, who also thought he could not go. Xiu Yuan summoned the military forces from various counties, and Pei Xia, the prefect of East County, led troops to Luoyang. Wang Sizheng asked him: "Now that the imperial court is in power and the royal family is declining, what should I do?" Pei Xia replied: "Yu Wentai enjoys a high reputation among the three countries, and it occupies a dangerous terrain where 20,000 people can resist 1 million people. With a spear in his hand, who would want to give it to someone else? Want to take refuge in Yu Wentai, just like just out of the tiger's den and into the tiger's den.

? "Wang Sizheng asked what to do. Pei Xia said, "If you plan to go to Gao Huan, you must have some misgivings. If you go west, you will be worried in the future. If the two evils are the lesser, it is more appropriate to go to Kansai for the time being and then consider it slowly. " Wang Sizheng thought Pei Xia's point of view was very correct, so he recommended him to Emperor Xiaowu, and Xiu Yuan appointed him as the left corps commander. Xiu Yuan asked his ministers what their plans were. Some say they want to go to Liang in the south, some say he Basheng is attached to the south, some say they want to go to Guanzhong in the west, and some say they want to stick to Luokou and fight to the death, so they can't decide at the moment.

? 27, Xiu Yuan sent messengers to recall Hu Sichun, and then led Nanyang Wang Yuanbao Ju, Qinghe Wang Yuanzhi, Wang Guangyang Yuanzhan with five thousand cavalry to camp in the west of turbid water. Hui Zhen, a monk under Nanyang King, followed with a thousand knives and a decree on his back. Everyone knows that Xiu Yuan is going to the west. That night, more than half of the people fled, and so did the king of Qinghe and Wang Yuanzhan. General tachileik, du, riding a horse to follow. Xiu Yuanda sighed and said, "It is not bad to know loyal ministers in troubled times!" On 28th, Xiu Yuan fled to Chang 'an, and Li Xian met Xiu Yuan in Yan County. On the 29th, Gao Huan entered Luoyang and sent Lou Zhao and others to pursue him, asking him to return to the east capital. Sun Ziyan didn't hold Shaanxi City, so he abandoned it and fled. Gao Aocao led the elite cavalry to pursue Xiu Yuan, all the way to the west of the mountain city, but failed to catch up.

? Yu Wentai ordered Zhao Gui and Liang Yu to lead two thousand chosen men to meet Xiu Yuan. Xiu Yuan walked west along the Yellow River and said to Liang, "The river flows east, but I go west. If one day you can return to Luoyang and personally sacrifice to the ancestral temple, it will be your credit. " The waiters were moved to tears. Yu Wentai prepared an honor guard and a guard, and visited Xiu Yuan at Dongyang Post. Yu Wentai took off his hat and said with tears, "I failed to stop the enemy's invasion and let the emperor drift from place to place. This is all my sin. " Xiu Yuan said, "Your loyalty and justice are well known. It's all because I have no virtue and let thieves run amok. I feel very ashamed to see you here today. Now I entrust you with the heavy responsibility of the country, you must work hard! " The soldiers shouted long live.

? Xiu Yuan entered Chang 'an and appointed Yu Wentai as general, Yongzhou secretariat and secretary, who decided military, political and state affairs. This regime was called "Western Wei" in history. Gao Huan found that he didn't catch up with Xiu Yuan, so he called civil and military officials to discuss who to make emperor. Finally, he decided to make Yuan, the eldest son of Qinghe, emperor. On October 17th, Yuan ascended the throne in the northeast of Luoyang, for filial piety and peace. This is the "Eastern Wei" regime. Throughout the Eastern Wei Dynasty, the political power was always in the hands of Prime Minister Gao Huan's family, and the contradiction between Hu and Han in kanto region was alleviated to some extent. The Eastern Wei Dynasty and the Western Wei Dynasty fought many wars and won and lost each other, thus laying the foundation for the division of the Northern Dynasty, and history entered the "post-Three Kingdoms era" at the end of the Southern and Northern Dynasties.
