Life is art. Art is life. I never separate it. I don’t feel that much anger. I equally have a lot of joy.

I never regret anything.

If I walk on the street, if I go to a restaurant, people come to me and say: "Can we take a photo together? Can you give me your autograph?" They would bring their expensive Armani or Prada wallet to sign. Other people who are desperate show me a photo of their dead daughter and ask: Can you support me? I tell them: How can I? Morally, of course, I sympathize with you. But I cannot support you and you cannot support me. This is the condition of this society. We are separated.

I see the Beijing National Stadium as an architectural project. I accepted Herzog and De Meuron's invitation to collaborate on the design, and our proposal won the competition. From beginning to end, I stayed with the project. I am committed to fostering relationships between a city and its architecture.

Now I've come to such a mixed culture: America, Europe, South America, Africa. And the politics are changing everywhere all the time and becoming even more unpredictable. There's no such thing as "fixed" culture. China is also becoming more global. Its problems are becoming international problems, becoming German problems, becoming American problems. Nothing is clear-cut. Perhaps I'll find my way - or get totally lost.

Imagine one day, the hateful world around you collapses. And it is your attitude, words and actions that put an end to it. Will you be excited?

Today, the general masses in this society are in this political-social condition that really encourages people to become rich and become a star and be unique.
