I've tried many websites to download this but they all don't work. If it's possible, could somebody with HOI4 on steam download it and send the file to me? Thanks.
Sorry if this isn't allowed or anything, I'll delete this if that's the case.
Might be able to DL it later today, but (assuming you're running a pirated copy of HOI4) I'm not sure you'd be able to actually install the workshop files without using steam's interface somehow. Have you tried joining their discord to see if they can provide you with any help?
One last thing: running the page through a machine translation it seems like the mod might only work if the language is set to chinese; have you tried that?
