I don't believe in a sense of home.

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.

Any design, any city, any kind of craziness or tragedy, it all comes from a long time of preparation.

If there's the right condition, I always want to express the concept or ideas in a very independent way.

[Cultural department] understand nothing but bureaucratic daily affairs. They don't care about culture.

New York is a city where you're so alone, you're an individual, you can disappear. You can make something happen. But it's very different to make something happen in the art world.
