哀帝
Later in 364, Former Yan launched a major attack against Luoyang, and Huan and Sima Yu considered a counterattack to relieve Luoyang. However, as Emperor Ai died in early 365, that plan was cancelled, and Luoyang soon fell. As he did not have a son, Emperor Ai was succeeded by his brother Sima Yi, as Emperor Fei. (Emperor Ai was preceded in death by his wife Empress Wang, as she died about a month before he died; they were buried together with imperial honors.)
