When travelling to China, one problem is that one cannot access WordPress, Gmail, Facebook and others.
One solution is to purchase a VPN to bypass the Great Firewall of China. Personally I use PureVPN, and it works. You can use it on both phone / PC / Mac (up to 5 devices).
If you have any other alternative methods, do post in the comments below! I have heard of alternatives like Tor / Psiphon but also comments that they do not work. Also, one should purchase the VPN before entering China, because once you enter China most of the VPN sites / mirrors are blocked by the highly intelligent Great Firewall (which uses machine learning, and also employs more than 50,000 workers to block the internet!)
