If this sounds trollish, then you'll have to excuse me, since I find it quite unbelievable for you to ask such questions in a void of information.
Yeah, you're coming across as preachy, there.

Frankly, everyone has their priorities, Brother, and though I'd like your help I certainly don't live for your approval. "Unbelievable?" Really? Considering some of the rank idiocy I see on these forums? But if you want more info:
This is for a cheap little one-off project, and this part of it is sort of what you'd only see very blurry in the background of a movie or something. I wanted to avoid the usual names only because they've been done so much and would stand out to anyone familiar with them as laziness on my part. Some alternate names of what were historically vassals or provinces as mentioned above would work just fine for me- I just don't want to use the names of any of the Warring Kingdoms- and I figured there'd be
someone who could just spit them out off the top of their head, here.
I have certainly answered similar requests. And in fact it isn't even alternate history- it's science fiction- but I figured if anyone could come up with appropriate names for culturally Chinese polities it would be here. I could manage Russian, but I would fail spectacularly and amusingly if I tried to produce Chinese names. It would be like the fake English writing you see on some counterfeit stuff- it sort of
looks right to a non-native speaker, but it's gibberish.
I tried to put the request in terms familiar to everyone here but, yes, it's not really alternate history so sorry if anyone feels misled. Does that help? So, it's a chance for someone to get creative...
