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.
Wang Zhang
In 936, during the reign of Later Tang's last emperor Li Congke (Li Cunxu's adoptive nephew), the officer Zhang Lingzhao (張令昭) mutinied at Tianxiong, expelled the military governor Liu Yanhao, and claimed the title of acting military governor. Wang served as the public works officer (in addition to being the treasurer) under Zhang during Zhang's mutiny. Soon, Li Congke sent the general Fan Yanguang to suppress Zhang's mutiny, and Fan quickly captured Tianxiong's capital Wei Prefecture (魏州) and executed Zhang. He also sought to find and execute Zhang's followers. As Bai Wenke was friendly with Fan's deputy Li Zhou (李周), Bai asked Li Zhou to save Wang. Li Zhou thus located and hid Wang, and had him delivered to Li Zhou's mansion at the capital Luoyang in secret and continued to hide him there.
