Emperor Ai of Tang
In 904, Zhu forced Emperor Zhaozong to move the capital from Chang'an to Luoyang, which was even more firmly under his control. Later that year, fearing that the adult Emperor Zhaozong would try to rise against him while he was away on campaigns against other warlords, he had Emperor Zhaozong assassinated. Bypassing Li Yu and the other older princes, he had an edict issued in Emperor Zhaozong's name creating Li Zuo crown prince and changing his name to Li Chu. Shortly after, Li Chu took the throne (as Emperor Ai). Empress He, who survived the assassination, was honored empress dowager.
Kuizhou
Kuizhou was part of Former Shu, founded by Wang Jian as part of the aftermath of the dissolution of the Tang dynasty: Wang was in control of Kuizhou in 907, when the Tang dynasty formally is considered to have ended. Kuizhou was part of Later Tang (one of the Five Dynasties which succeeded each other in control to the north of China), after its conquest of Former Shu, in a southern extension of power.
