Historically, great rulers used to cherish ministers who spoke harsh truths.

‌I guess that is incredibly difficult.
Well... honestly, let's say we acknowledge their initial sincerity in wanting to become a great leader.
In that case, they should get rid of all those sycophants—those people like the eunuchs who only say sweet things and flatter the ruler, causing them to close their ears and eyes.
They shouldn't even be allowed to get close~~~
They should appoint upright people who are capable of pointing out their mistakes, even if it's unpleasant to hear.
I suppose it's not as easy as it sounds.
Is it that hard??
I assume there are intense power struggles and rewards for merit in that world as well?
Since those things cannot be ignored, they probably struggle with whether or not to appoint trashy individuals as ministers.
If they could just handle personnel appointments well, they would be halfway there...
