（丁卯）　懷帝熾改永嘉（字豊度。武帝二十五子也。生而姿奇。後無罪為劉聰虜之。壽三十歲）治六年。

(Dingmao) Emperor Huai, Sima Chi, changed the era name to Yongjia. (His courtesy name was Fengdu. He was the twenty-fifth son of Emperor Wu. He was born with extraordinary demeanor. Later, though blameless, he was captured by Liu Cong. He died at the age of thirty.) He ruled for six years.
