Perhaps the only reliable way to get your social network and social media fix is to use a VPN or Virtual Private Networks in China.
Its not that hard to set up and requires just a little technical setup and can be done on windows with a little effort. You can do the same on Linux or even your phone without too many headaches. There are plenty of guides online and we suggest that you use them. If you are travelling for business, ask your local freindly network engineer to help you or to setup using the corporate VPN.
Once you have your VPN setup its simply a question of connecting to the internet in the usual way, which is often using Wifi, esp on holiday or you might be using ethernet to get online.
Good luck and happy browsing and enjoy your time online.
