甘南藏族自治州
In 683, Li Xian was moved from Chang'an to Ba Prefecture (巴州, roughly modern Bazhong, Sichuan). In 684, after Emperor Gaozong's death, Li Zhe initially took the throne (as Emperor Zhongzong), but soon was deposed himself due to signs of disobedience to Empress Wu (now empress dowager), and Li Dan became emperor instead (as Emperor Ruizong), although Empress Dowager Wu retained all powers as regent. In spring 684, she sent the general Qiu Shenji to Ba Prefecture with the order of, "Examine the house of Li Xian the former crown prince to prevent external attacks." However, she hinted to him that he should have Li Xian killed. When he got to Ba Prefecture, he placed Li Xian into a small room and forced him to commit suicide. When news of Li Xian's death arrived at Luoyang, Empress Wu publicly blamed Qiu and demoted him to the post of prefect of Die Prefecture (疊州, roughly modern Gannan Tibetan Autonomous Prefecture, Gansu), while publicly mourning Li Xian and posthumously creating him the title of Prince of Yong. (Qiu was soon recalled to Luoyang to again be general.) After Empress Wu's death in 705 and the restoration of Emperor Zhongzong to the throne, Emperor Zhongzong had Li Xian's casket returned to Chang'an, to be buried near the tomb of Emperor Gaozong. After Emperor Ruizong became emperor again in 710, he had Li Xian's crown prince title restored.
