“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.”

“Widespread state control over art and culture has left no room for freedom of expression in the country. For more than 60 years, anyone with a dissenting opinion has been suppressed. Chinese art is merely a product: it avoids any meaningful engagement. There is no larger context. Its only purpose is to charm viewers with its ambiguity.”

“Now the British are coming. I think Cameron should ask the Chinese government not to make people 'disappear' or to jail them merely because they have different opinions.”

“If my art has nothing to do with people's pain and sorrow, what is 'art' for?”

“The Chinese art world does not exist. In a society that restricts individual freedoms and violates human rights, anything that calls itself creative or independent is a pretence. It is impossible for a totalitarian society to create anything with passion and imagination.”

“As a person, I was born to give out my opinions. By giving out my opinions, I realize who I am. As long as I can communicate, I'm not so lonely. If I cannot travel, or do art, or have company, if they take away all my belongings, it doesn't matter at all.”

“I think Chinese leadership is trying to tell the world they have another set of logic or reasoning or values which are different from yours. Of course, I don't think they believe that. It's just an argument that's made when you can't confront the truth and facts. They really want to maintain power.”

“The American experience influenced my understanding of individuality, basic human rights, freedom of expression and the rights and responsibilities of citizens.”

“China has not established the rule of law and if there is a power above the law there is no social justice. Everybody can be subjected to harm. I'm just a citizen: my life is equal in value to any other. But I'm thankful that when I lost my freedom so many people shared feelings and put such touching effort into helping me.”

“I call on people to be 'obsessed citizens,' forever questioning and asking for accountability. That's the only chance we have today of a healthy and happy life.”
