John, foreign VPNs are outlawed in China. You should use them with caution in this country. Under no circumstances should you visit local website through a VPN. What would I do if I hadn’t taken care of VPN in advance? As a rule, the websites of VPN services are available. I recommend contacting customer service and asking if they work in China and what is the best way to register being in this country. Some VPNs have mirror sites for China. Within one comment I won’t be able to respond in detail. The additional information is in our review dedicated to VPN providers for China.
