Not really that many, very few in fact, compared to the mass of other BL games, but more than one is victory(?)
And yes, it can be done, there are pretty many folks who own VPNs in China, but I'm not one of them. That thing is banned in our country so it isn't too easy to find, and when I do find one, its price drove me back to not using VPN at all...Although I feel like everyone has one but me...I've been looking for ways, but haven't found one yet. I can visit AO3 too tho, we've got quite a few mirror websites, it's just there may be security problems.
