China blocks most VPN services. The vast majority of VPN developers don't care if their service works in China or not, as many of them are built for secure Internet connection only.
At ZGC VPN, we use special technology and locations for servers to achieve a seamless connection. You can just try it for free to see for yourself.
Our servers are located all over the world: Japan, Singapore, Russia, India, USA. On the "Premier" tariff you can choose any country in the world as you wish. The program will automatically switch to a faster server.
