VISA help? Travelling to China to visit girlfriend who is working there for 8 weeks

Hey hey, so I’m thinking of travelling to Shanghai for about a week to visit my girlfriend who is working there for 8 weeks with a musical. I’ve been looking on here for advice about visa’s and I originally thought I would have to get a tourist visa, however I’ve read that you need to provide details of your booking for a hotel. My partner is being put up in a hotel by her company and as it wouldn’t be myself who has booked it and I’d be sharing her room, do I need to go for a different visa that clarifies I’m visiting someone who is working in China? Or do I go for the tourist visa and just show the proof of booking by her company which would look like an 8 week stay and not list my name?

Any help would be appreciated (even if it’s to help explain my case a bit more)
