I've been watching a great Chinese drama series on YouTube called "The Confidant." It's all about eunuchs during the reign of Empress Cixi at the end of the Qing Dynasty. If you don't mind subtitles, you'll probably enjoy this. 33 episodes + plus another spin-off series called "Short End of the Stick" after that.
