Later, Yuan Yijing's brother Yuan Laichao rose up against Ping Qingsheng. After learning the news of his brother, Yuan Yijing led more than 300 people, including Benkei Musashibo, a retainer, to deal with Ping Qingsheng with his brother. After a series of fierce battles, Yuan Yijing achieved great results, which showed his superb military command ability. Coupled with his high martial arts, he completely defeated his brother and caused his brother's jealousy. Ping Qingsheng was chased by his brother after his death, and committed suicide when there was no escape in Gaoguan where he lived. Before committing suicide, he personally killed his wife, the township commander, and his daughter, the turtle crane commander. His beautiful concubine, Shizuka Gozen, also had her hair cut off after Yuan Yijing's death, and soon died. From then on, Japan began the era of Kamakura shogunate, and Yuanlai was the first general of Kamakura shogunate.
Such a hero who had a rough experience and ended in tragedy won the general sympathy of the Japanese people. Nobody wants him to die, and neither does he. So the story came out. It is said that Xuanji didn't die, and left a letter similar to Taro Sugimoto to the corpse body double in the high hall. He fled north with his retainer, crossed the sea into Riccardo Chailly Island (Hokkaido), then came to Korea via Sakhalin Island, entered Mongolia, and finally became Genghis Khan. Most people just listen to stories, but some people take them seriously. During the Meiji period, Kenichi Morimatsu, then the cabinet minister of Ito Bowen, collected Genghis Khan's statement in his graduation thesis at Cambridge University, and later wrote a book, I Ching Revival. 1924, Koyabe Quan Yi Lang, who studied at Harvard and Yale University in the United States and obtained a doctorate, personally went to the northeast of China for a field trip, and later published the book Genghis Khan as a righteous source. There are many more, so I won't go into them one by one.
None of their evidence is true, just their own feelings. First, Yuan Yijing and Genghis Khan lived in the same era, both of whom were sons of tribal leaders. After his father died, he revenged his father. Second, they are all outstanding in military exploits, noble in character, deeply loved by their subordinates, and brave and good at fighting. Third, Yuan Yijing and Genghis Khan have similar pronunciations. Bian Xiao doesn't know Japanese, and he can't read it. Fourth, Yuan Yijing's family emblem is almost the same as that of the Mongolian Empire. Fifth, after Genghis Khan's death, his grandson Yuan Shizu Kublai Khan attacked Japan to avenge his grandfather, because China had never taken the initiative to attack Japan before. This is nonsense. I was backward in sailing before, so I risked my life to go to Japan. Where can I take the initiative? For example, Jian Zhen, a monk in the Tang Dynasty, made six trips to the east and went through hardships before reaching Japan. Why are so many Japanese keen on the myth that Genghis Khan is Japanese? Maybe they want to recognize a celebrity as their ancestor, so that they can have a bright future and satisfy their vanity. Maybe it's an ulterior motive.
