With 1.3 billion people and the world's fastest growing economy, the People's Republic of China (PRC) is a modern economy miracle. But for all the commercial freedom and success available in China since economic reforms which began in 1978, political freedom has remained much more elusive. The government of China maintains a repressive set of Internet restrictions; but obtaining a proxy server in China can provide one way to scale the Great Firewall of China.
Investigate and compare available proxy servers. The websites of many free and commercial proxy server services will be blocked, so try to visit the websites of several to see which websites are accessible. A possible comparison tool is serverwatch.com/stypes/compare, which allows the comparison of several types of servers including proxy servers.
Download a proxy server--from among those accessible--based on your preferences. Note that using proxy servers carries the risk of having passwords and user names hi-jacked by the proxy servers owner. Take caution when using a proxy server to access a private or financial account, and only use proxy servers of reliable integrity.
Visit a website and ping your IP address to see it identifies your location as China. One such website is whatismyipaddress.com but there are several other such sites available.
