Sima Rui s father is not surnamed Niu

I have seen other people's research that Rui Mu and the little official surnamed Niu had an affair.

Sima Rui (27 May 276 – 3 January 323), also known as Jingwen, was a native of Wen County, Hanoi County (now Wen County, Henan), and the founding emperor of the Eastern Jin Dynasty (reigned 318-323). The great-grandson of Emperor Xuan of Jin Sima Yi, the grandson of Sima Ling, King of Langya, the son of Sima Jin, King of Langyagong, and the son of Emperor Wu of Jin.

In the first year of Taixi (290), he attacked the king of Langya and participated in the crusade against Sima Ying, the king of Chengdu. After losing the battle, he left Luoyang and returned to the feudal country. Emperor Huai of Jin ascended the throne and worshiped General Andong and supervised the military of Yangzhou.

After closing the swim, he followed Wang Dao's advice, crossed to Jiankang in the south, and befriended the Jiangzuo Shi clan. In the seventh year of Yongjia (313), he worshiped the prime minister and the governor of the Chinese and foreign military. In the Yongjia Rebellion, Emperor Jin was captured, and the Western Jin Dynasty perished.

In the fifth year of Jianxing (317), under the support of the Jin Dynasty clan and the great quarrel between the north and the south, he was enthroned as the king of Jin (Eastern Jin Dynasty), and the year name was Jianwu. In the first year of Taixing (318), he officially ascended the throne, known as Emperor Jin Yuan in history, and opened"The king and the horse share the world"situation.

On the 10th day of the 11th month of the first year of Yongchang (January 3, 323), after the rebellion of Wang Dun, he died depressed, at the age of forty-seven, he was buried in Jianping Mausoleum, called Emperor Yuan, and the temple was called Zhongzong.

In the last years of the Western Jin Dynasty, there were constant disputes in the world, and Sima Rui also crossed the Yangtze River to Jiankang at this time. After coming to Jiankang, he relied on his clan identity and ability to make extensive friends with the scholars in the Jiangzuo area, and his power continued to grow. After the fall of the Western Jin Dynasty, the powerful Sima Rui was proclaimed as the new emperor, and the Eastern Jin Dynasty was established.

Sima Rui is not the son of Sima Ji and Xiahou Guangji, but the son of Xiahou Guangji who fornicated with others. "Xuanshi Tu" records many prophecies of the Wei and Jin dynasties, including the prophecy of "Niu follows the horse", the angry Sima Yi ordered the killing of many people with the surname Niu, but the prophecy still came true, Sima Yi's grandson Sima Ji married Xiahou Guangji, who did not abide by women's morals, and she had an affair with a surnamed Niu Xiaoguan to give birth to Sima Rui.

Sima Rui is the grandson of Sima Yi's son Sima Ling. Because at that time, Wei history recorded that Sima Rui was born to him by his mother by fornication with a person surnamed Niu.

Emperor Jin Yuan was the son of Sima Jin, the king of Langya Gong.
