Why Murong Clan fell into the strange circle of restoring the state

In the 4th century A.D., the Murong clan of Xianbei, who lived in Liaodong, established the right of Former Yan through several generations and unified almost the whole north, becoming the first strongest state at that time. However, the good times did not last long, and soon Qianyan was destroyed by the former Qin Fu Jian. Former Yan was founded by Murong Wu in 337 A.D. and lasted for 36 years through three generations before it was destroyed by the Former Qin in 371 A.D.. Its three emperors were Emperor Taizu Wenming, the founding emperor Murong Wu, who reigned for twelve years (377--348); Emperor Liezu Jingzhao, Murong Jun, son of Murong Wu, who reigned for thirteen years (348--360); and the last one was Emperor Murong Wei, the Emperor of Lieyu, who reigned for eleven years (360--371). After the demise of Former Yan, Murong Clan always remembered to restore their ancestry. Murong Chui became the king of Yan in 384 AD, and two years later he became the emperor of Later Yan. Murong Chui reigned for thirteen years (384-396). After that, Murong De founded Southern Yan in 398 AD, which lasted 14 years, and Murong Chong founded Western Yan in 385 AD, which lasted 9 years. In this way, the Murong family established four dynasties during the period of the Five Hu and Sixteen Kingdoms, but all of them were short-lived dynasties.　　　　 It was also the Murong family's pride and restlessness that led to the establishment of several dynasties in that chaotic period. Liu Yu, a powerful minister of the Eastern Jin Dynasty, decapitated more than 3,000 members of the Murong clan after destroying Southern Yan. The Murong family has since disappeared from history.　　　　 So is Murong Fu in Jin Yong's writing trying to restore these dynasties? Is Murong Fu a real person? The old ancestor of the Murong clan, Murong Nguibai, led his clan in 239 A.D. and defected to Cao Rui, the Ming Emperor of the Northern Wei Dynasty, and the old family, the Sima family. Cao Rui, the Ming Emperor of the Northern Wei Dynasty, crowned Murong Hubert as the King of Ruyi. After his death, his grandson Murong Shibuqui was named Grand Monarch of the Xianbei by Emperor Wu of the Jin Dynasty because of his great achievements in conquest. Murong Shugui moved his troops to Liaodong. Murong Shugui had two sons, the first son, Tugukhun, and the second son, Murong Man, and after Murong Shugui's death in 284, his first son, Murong Man, succeeded to the throne. The second son, Tugukhun, set up his own family and moved westward to Qinghai and Gansu. In 312 A.D., the Tugukhun and Gao Han established a state with a territory stretching from Gansong in the north to Bailan in the south, and from Taohe River in the east to ütian in the west. In 663, it was destroyed by Tubo.　　　　 The history of Murong Fu, is the last descendant of the Tugukhun dynasty to inherit the title. From this point of view, Murong Fu is not the same person as Jin Yong's "Gusu Murong Fu". Because Murong Fu, itself is the last king, there is no restoration. After the death of Murong Fu, the title is still broken, Tugukhun incense is broken. Murong man is the father of the first emperor of the former Yan, Murong Wu.
