We live in an effective and convenient era. All our desires can be satisfied just with the internet connection and electricity. This October, I need to do some research online, suddenly found that VPN has been blocked. At that moment, I came to realize that though I am definitely one of the world people, it seems I am not really belong to the world. There are only 4 countries left in the world which is not free with Internet service, there has no Facebook, no Twitter, also, no Youtube. Actually, the problem is not only about internet, it is about human rights. That is our Human beings, we need not only food, but also freedom. Now it is 21 Century, people from some countries are still live in beautiful cages, though the cage is such wide and rich of resources.
