However, the eunuch's representation in history was rarely as positive. If one were to believe everything written in Chinese history books, says Bates, one would get the impression that all eunuchs were corrupt and cunning, using their influence to a negative effect, and 
getting rich through bribery and corruption. One would also believe they smelled, because of their difficulties in effectively passing water following their castration, that they spoke with high voices and that they were effeminate. While undoubtedly corruption did occur amongst some eunuchs, it cannot explain their universally poor portrayal in historical texts. Liu suggests that their bad representation in history books and records was because these were written by senior officials, who would naturally be envious and bitter about the influential position of the eunuchs.
