The first exhibition that I used bright colours in painting the room was at a gallery in Paris, and there were seven rooms in the gallery. It was very nice gallery, not very big rooms, around the courtyard, it was a very French space. So I painted each room in different colour. When people came to the exhibition, I saw they came with a smile. Everybody smiles - this is something I never saw in my work before.

When I was teaching I often said to students that you are trying to be too creative, don't be too creative, because there is so much already in what you are making, you don't need to do very much. You just need to do a little bit, and that is a lot.

I was poorer than anyone I'd ever met. But it was a great time to be a young artist - I remember it as a period of exceptional creative freedom and adventure, when one was regularly presented with works of art unlike anything one had ever seen before.

I've taken away everything I could think of, and yet what remains is enough. These days many more people come to my work, and once they see my work they will always recognize it.

Art is more to do with observation than invention.

When I was invited to go to Wuhan, I didn't know anything about it, so I looked up the Wikipedia about Wuhan. I discovered that part of Wuhan used to be Hankou, and then I realised that my great grandmother came from Hankou. My grandmother and father were both born in Hankou. Of all the places in China, it is the most amazing place to have asked for my exhibition. I needed to go back where my family comes from!

I am trying to present objects in the simplest way possible, and I don't want to supply too much context.
