I expect that Wuxia, Xianxia, and Xuanhuan are three different genres.
It is funny that people get those shuffled so much. I guess its just that naming conventions are different.
I've said before that it isn't that hard to mix them all together, and I kinda of mean it. The hardest would be putting more of the historical aspect of Wuxia. You may just tell a story with several cultural settlements and all have some sort of cultivation or not. This way you dab into Xianxia and Xuanhuan. One of the main topics about Xianxia is the immortal shenanigans (which kinda of puts people into those infinite storylines), but nothing actually impedes that this follows a lower form of fantasy, and even a more slice of life/contained form to it.
What kinda of itches me about Cultivation and Xianxia in a whole is that people mostly follow tropes mindlessly and repeat the same formula endlessly. There's a lot of potential into the ideas that surround the setting and genre but most of them are neutered to enter specific boxes. People seem to get a hold around nomenclature and tropes, but instead of working with them and twisting them for something new, they just slap it on top of their story and call it a day.
Those are things I can take from many of the comments out here. It leaves me guessing: is it something inherent to the genre and its structure, or is it that this new model of publication (online, independent and most of it in amateur style) amplifies these effects?
(and just to contextualize...here in Brazil we have nothing similar to SH, RR, Narou, or whatever. The closer we have is a version of Fanfiction.net and a shittier Wattpad. I say this for a reason: because of the lack in this online market we kinda of...simply never had to deal with these things I speaking about

! We have
zero exposure to cultivation, xianxia, litrpg, and I think the only popular trending genre we get is Isekai, but only 1 novel in the market deals with it)
