崔胤
After Emperor Zhaozong returned to Chang'an in 898, there was an incident in 900 when the powerful eunuch Liu Jishu deposed the emperor and briefly replaced him with his son Li Yu, Prince of De the Crown Prince, before a countercoup restored Emperor Zhaozong to the throne. Still, the episode portended further struggles between eunuchs and imperial officials, led by the chancellor Cui Yin. Zhao did not want to be involved, so he claimed to be ill and retired to the eastern capital Luoyang, refusing to meet any guests for several years.
