Censorship is saying: "I'm the one who says the last sentence. Whatever you say, the conclusion is mine." But the internet is like a tree that is growing. The people will always have the last word – even if someone has a very weak, quiet voice. Such power will collapse because of a whisper.

I deal with students every day - from China, Germany, the United States, Hong Kong and Taiwan. And I've noticed that the Chinese students are the least trained in having a sense of aesthetics. They lack any ability to sense what is beautiful or what is proper. They can be learned and skillful, but they lack the ability to make their own free judgment. It is really sad to see young adults of 20, 25 years who were never taught to make their own decisions. People who can't do that don't get a sense of responsibility. And if you lack a sense of responsibility, you push the blame onto the system.
