  Virtual private network is a tunnel connection from outside network to a LAN .
  Let me give you a real life example.
  Consider you drop a paper mail to some guy in some location say address xyz.
  Now the content of you mail will not change if I put your mail in another envelope and encrypt it and again destined to xyz.
  
  Only the person, who knows the encryption will be able to open the outer envelope to read the mail in the inner envelope.
  In simple words this array of outer envelopes is VPN.
  
  In a VPN service, you establish a secure tunnel from outer network (A)to an LAN network(B) over internet and you should be then able to use all the service provided in the inner network. You might ask why don't we directly use internet to access that LAN? It would not work- because the firewalls of the LAN (B), would not allow any packets to access the inner services whose say source address is not what is expected.
  
  And as far as Chinese accessing Goggle through VPN is concerned , I think the % can be so less- given the popularity of BAIDU there 😉. They might be connecting to servers in Hong Kong ( HK has not banned Goggle as far as I know)

  I think you can use Proxy Servers. But then I don't know much about IT and CSE.

  exactly right.
  
  And, as raj said you may use web proxies to access blocked sites. For example, some colleges block social networking sites like orkut, facebook etc. Then you may use some proxies like power.com etc. By using that proxy you may access that blocked social networking sites. some other proxies are hidemyass.com, anonymizer.com, wujie.net etc. We have so many types of proxies.
  
  So, you may access any kind of blocked site using proxies.
