The ancestors of the Yuan Dynasty were originally named Mongolia, and their country was north of the Jurchens. They took the three characters Qiwowen as their surname. There is an ancestor named Alan, who lives as a widow in the extreme northern desert. Light often shines in her belly, and she gives birth to three sons. Ji Zi said that Bo Duan Yi'er was tall and tall, but Shen Yi was taciturn. Later, the descendants became prosperous and did not belong to each other. It was passed down to the ninth generation grandson, who said that it was time to attack the Tata'er tribe, and won a great victory. He captured his minister Temujin and returned. It was soon time to give birth to a son, so he named him Temujin and aspired to martial arts. Temujin was profound and had a great strategy, and he used troops like a god. He destroyed more than forty kingdoms in Xixia and became more powerful. He proclaimed himself emperor at the Onan River and named him Genghis Khan, making him Taizu. From Taizu, Taizong, Dingzong and Xianzong, it was passed down to Xianzong's mother and brother. It was said that Qiwo Wen and Kublai Khan succeeded to the throne. He was the ancestor of the world and changed the Yuan Dynasty to the Yuan Dynasty.
