During old times, Eunuchs were castrated, meaning their scrotum will be removed. Some died since the medicine back then is not that great, while some lived for some time but died from infections or complications. Eunuchs are not considered as male nor they are female. You will see some historical texts and illustration of some officials having sexy time with eunuchs. Since their scrotum are removed, they gradually became *feminine*. Eunuchs sometimes wear rouge, perfume and other cosmetics. The reason why they are castrated is to prevent them from having any affairs to the emperor's harem (prevent them from having any thoughts towards the emperor's women/men).
