Tell me the big story of Guan Yunchang, and by the way, why Guan Yu has a greater influence on future generations.

Guan Yu (165-220), whose original name was Changsheng, later changed to Yunchang, was from Hedong Jie (now Yuncheng, Shanxi). A famous general during the Three Kingdoms period, he followed Liu Bei since he gathered people in the countryside to raise troops. He was one of Liu Bei's most trusted generals. After Guan Yu's death, his image was gradually deified by later generations. He has always been the object of folk sacrifices and was honored as "Guan Gong". He also received praises from successive imperial courts, and in the Qing Dynasty he was regarded as "the god of loyalty, righteousness, martial spirit, benevolence, bravery and majesty". "Emperor Guan Sheng" is revered as the "Martial Saint" and is as famous as the "Literary Saint" Confucius. The long historical novel "The Romance of the Three Kingdoms" also contains many descriptions of Guan Yu's deeds. In "The Romance", Guan Yu is described as the first of the "Five Tiger Generals", and Mao Zonggang calls it "the most righteous" among the "Three Wonders of the Romance" . In addition, there was a place named Guan Yu in ancient times, but its exact location is unknown. Introducing the story of "Three Brothers in Taoyuan", Luo Guanzhong placed it in the first chapter of the opening chapter of "The Romance of the Three Kingdoms", "The Banquet of Three Brothers in Taoyuan and Killing the First Yellow Turban Hero for Meritorious Service". The article describes Liu Yan going out to recruit volunteers. The article describes Traveling to Zhuoxian, he attracted Liu Bei, a hero in Zhuoxian. Then by chance, Liu Bei met Zhang Fei and Guan Yu. The three had similar interests and hit it off and became brothers. At the end of the article, the three people burned incense and bowed before saying an oath: "I remember Liu Bei, Guan Yu, and Zhang Fei. Although they had different surnames, they became brothers and worked together to rescue the poor and help the people in danger. They reported to the country and made everyone safe. Don't ask for the same year. Born in the same month and on the same day, I only wish to die in the same year, the same month and the same day. The emperor and the empress have realized this. If they are ungrateful and ungrateful, they will be killed by heaven and man!" After the oath, I worshiped Xuande as my brother, Guan Yu as my second, and Zhang Fei as my younger brother. The Romance of the Three Kingdoms vividly describes the story of the three sworn brothers in Taoyuan. So in real history, what is the relationship between Liu Bei, Guan Yu and Zhang Fei? Chen Shou's "Three Kingdoms - Biography of Guan Yu" records: "The first master and the two of them slept in the same bed, and they were as kind as brothers. But the people in Chou sat wide and stood around all day long, following the first master and not avoiding hardships and dangers."; "Three Kingdoms - Biography of Zhang Fei" It is mentioned in the book: "Yu is several years older than (Zhang Fei), and brother Fei takes care of him." "The Chronicle of the Three Kingdoms - Liu Ye's Biography" also says: "Guan Yu and Bei are righteous rulers and ministers, and they are as kind as father and son." These three historical data are enough to explain the two sides. A question: First, the relationship between Liu, Guan, and Zhang was "enruo brothers"; secondly, they were "enruo brothers" rather than sworn brothers. There is no such thing as sworn sworn relationship in historical materials. However, it has been widely circulated among the people that the Three Peach Gardens were sworn brothers, especially after the Romance of the Three Kingdoms, it became known to all women and children. Therefore, with the addition of the "Three Peach Gardens", the relationship between Liu Guan and Zhang became even closer. "The Romance of the Three Kingdoms" has been widely circulated since its appearance in the late Yuan and early Ming dynasties to the middle of the Ming Dynasty, and had a great impact on all social strata. Guan Yu's image of loyalty has also been deeply rooted in the hearts of the people. Rulers of all dynasties strengthened feudal rule by building Guan Gong temples. Along with Guan Yu's status in official religion, it is also becoming increasingly popular among the people. As early as the Ming Dynasty, Guan temples were said to be "all over the world". "His words can be heard in Jingjing, and the drums and bells can be heard by each other. The number of Guan temples has increased with each passing year." By the Qing Dynasty, there were more and more Guan temples. There is a saying that "there are more than 10,000 Guandi Temples in the world", and it is said that "Nowadays, outside the Antarctic Ridge and the North Pole fortress, there are no children or women who can't help but be shocked by their power. The prosperity of the incense will be as immortal as the heaven and the earth." Emperor Yongzheng also believed: "From Tongdu Dayi down to the remote land of Shanyihaihao village and ruins, the people from the loyal ministers and wise men who admire virtue and uphold righteousness, down to Foolish men, foolish women, children and foot soldiers are humble, and they worship the appearance of temples, run around praying, and look with respect and respect, as if they have seen it." "Yun Chang is also a true righteous man! "Cao Cao's words reflect Guan Yu's loyalty. Now all "communities" worship Guan Yu's appearance characteristics. "The Romance of the Three Kingdoms" describes Guan Yu's appearance as: "Nine feet long, two feet long beard, face like a jujube, lips If you apply grease, you will have red phoenix eyes and lying silkworm eyebrows, and you will have a majestic appearance." His red phoenix eyes and lying silkworm eyebrows are rare in the world. The phoenix eyes are majestic, and the lying silkworms are like mist, and they are heroic and domineering. It is said that when his red phoenix eyes open, Just to kill people. Guan Yu has a beautiful beard, is an enemy of ten thousand people, is loyal and loyal, and is good at reading Zuo's Spring and Autumn Annals. When he surrendered to Cao Ying, he was treated well by Liu Bei.

He even scraped bones to treat poison. When Guan Gong attacked Fancheng, he fought with Pang De. Pang De pretended to drag his sword, but secretly fired an arrow and injured his left arm. After that, Guan Gong killed Pang De and imprisoned him. When he attacked Cao Ren, He was injured by an arrow from the city guard and hit his right arm. The arrow contained medicine and the poison had penetrated into the bone. His right arm was bruised and swollen and he could not move. The famous doctor Hua Tuo came to diagnose him and said that he needed to scrape the bone to remove the poison before he could recover. Guan Yu immediately stretched out his hand. Hua Tuo treated his arm and began to scrape the bones, and the blood flowed into the basin. However, Guan Yu was eating meat and drinking wine while playing chess with Ma Liang (everyone who saw him above and below the tent covered their faces and lost color), with a calm demeanor and seemed to have no pain.
