I had a long holiday in China recently. It had been a fun and eyes opening trip. Feels like the whole nation is in the middle of a “technology revolution”. Among all, Internet has become one of the core driving force. But while Wifi beomces a life essential here, the infamous Great Firewall (GFW) is also getting more effective. After tried numbers of paid and free VPN providers, I just could not find a reliable VPN service to simply let me post a picture on Facebook.
