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.

I wouldn’t say I’ve become more radical: I was born radical.

My understanding of Chinese history is limited. So far, I have only scratched its surface; I wish I could find out more.

We should use this public sphere and redefine - beyond China's borders - what a government is allowed to do, where its powers end and where the realm of a citizen's privacy begins.

As a total activity - I practice curating, art, architecture, writing, and publishing all together. I still act as a living creature.

Overturning police cars is a super-intense workout. It’s probably the only sport I enjoy.

I spend a lot of time talking to journalists.
