All the above can be passed smoothly, and then it is possible to become a eunuch. This position is basically the eunuch's dream position. Every eunuch has worked so hard to get from the position of eunuch to this position step by step. Therefore, if someone asks the eunuch to call her father-in-law, the eunuch must feel looked down upon.
Eunuchs have more power. If anyone annoys him, there will really be no good life after that. It's good to be a eunuch. It is enviable to be a eunuch in charge. Therefore, the ancients really loved and hated eunuchs, and even many court officials had to have good relations with eunuchs.
Just because there are few eunuchs who can read the imperial edict does not mean that all eunuchs can read the imperial edict. Looking at the imperial edict's high status of eunuchs, we can understand why people at that time were more afraid of eunuchs and tried their best to please others. Inferior eunuchs can only read some letters to their concubines. Of course, not all the imperial edicts can be read by eunuchs, and the status of eunuchs is not that high.
Therefore, the eunuchs in ancient times were not just people who had no education and no money in our memory. On the contrary, those who can work in the palace still have a high threshold, and they can't be employed casually.
