I know nothing of ancient Chinese history but when I read a little

>Why are there so many eunuchs in China?
Emperors needed somebody close to them/his royal family that could manage their harem but not fuck his wife or concubines. If you had a dick the potential to humiliate the king was always there.
>Why were people castrated and why/how did they serve the emperor?
Mostly with the royal harem
Often a concubine would give birth to the next emperor so they were pretty important. A kid that was the son of somebody else but thought to to be the child of the emperor could be brought under his biological dads influence which could destroy the entire empire if he was shit.

Chinese peepees are so small they can't tell the difference between a normal "man" and a eunuch

How did the ones being castrated feel? Was it honorful or a punishment?

China "man" have little tiny peepee, almost useless. Not take much effort to remove. Not see much use if not removed. With cost relatively low, usage relatively high.

Well they couldn't fuck anymore so I imagine it was humiliating in that regard but they still very influential and held a lot of power.
In Qin Shi Huang's era the royal eunuch had enough influence to conspire with his mother to attempt to overthrow him.

they mostly served admin roles and as bureaucrats. Under the Ming their power was left pretty much unchecked and they had massive influence over the silver currency in the country
