Because his biological mother, Zheng Achun, kept a pet, the Jin and Yuan emperors especially loved Sima Huan. At the beginning, he was adopted to Sima Hun, the younger brother of the Jin Emperor, and Hou Ting, a native of Changle, was later named Yi Tinghou. Shang Shu ordered Diao to play, saying, "In the past, Duke Linzi of Wei took Xing Yong as his home, and Serina Liu was an illegitimate child. Since you are young and weak, you should choose Mingde. " Emperor Jinyuan ordered: "There are thousands of households in Linzi, and there are very few talents who can travel with Tian Su. I am very weak tonight, why not talk about it! I sealed this son from time to time and didn't like children. A dead brother should be an heir, not an ear. Jia Cheng and an illegitimate child are enough to take a photo of the shrine sacrifice, and Qu Xian is useless! " In the first year of Daxing (3 18), Sima Huan fell ill, and Si Marui returned the grain for him. He was appointed the evil Lang Wang and died shortly after his successor was two years old. Posthumous title mourns (evil spirits mourn the king).
Emperor Jinyuan mourned the loss of his life and was buried. Sima Huan sealed the nations and gave them adult gifts. He wrote a letter to the macho man, prepared good or bad clothes and set up a cemetery, which made great contributions. In 2003, the tomb of Sima Huan was discovered in Linyi City, Shandong Province, and was buried with the wife of Sima Huan's mole and his brother's son Lang Xie, who mourned Wang Sima Anguo.
In the first year of Yongchang (322), Sima Huan's mother and brother Sima Yu were appointed as the evil king, namely Jian Wendi. In the second year of Xianhe (327), Sima Yu moved to the title of King Huiji, and Sima Yue (Jin) was the evil king. Emperor Kang of Jin acceded to the throne, and Sima Pi (Emperor Ai of Jin) was the evil king. When the emperor succeeded to the throne, Jin abolished the emperor as an evil king. Jin Fei acceded to the throne, taking Sima Yu () as a photo, and worshiping Lang Xie Guo. Jian Wendi went to Langchang, and the country had no children. Jian Wendi was on the verge of collapse, and the youngest son, Sima Daozi, was named the evil king. In the seventeenth year of Taiyuan (392), Sima Daozi was the King of Huiji, and Sima Wende (Emperor Gong Jin) was even regarded as the evil king. After Gong Jin ascended the throne, this evil country was wiped out.
