Wait, are really there that many MDZS games? I've only found five so far, excluding the fanzine. But then again, I'm only looking for English language games to link to in my socmed, so there may be a limit as to what I'm seeing. A number aren't tagged, so I have had difficulty finding them.
It's a bit odd that you don't have access to Reddit and Twitter because I know a number of mainland Chinese people who're on both these platforms. I've got a number following me and interacting with me on both platforms so I know they exist. Perhaps try a VPN or look up ways to circumvent the block? There are folk from China offering to translate my fics and post them on Lofter, so I know it can be done because AO3 is blocked in your country and they've been able to send me messages.
