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.

We see the tendency in the world to criticise democracy and sometimes even to say that authoritarian countries like China are more efficient. That is very short-sighted. China looks efficient only because it can sacrifice most people's rights. This is not something the west should be happy about.

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.

Chinese citizens have never had the right to really express their opinions; in the constitution it says you can, but in the real world it is more dangerous. In the west people think it's a right they're born with. Here it's a right given by the government, and one that's not really practised.

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

A happy wife is a happy life.
