SPIEGEL: Chinese fighter jets have been flying over islands in the East China Sea since November, a few weeks ago a Chinese spacecraft landed on the moon -- and now a Chinese helicopter rescued a group of tourists in Antarctica. China is looking pretty strong and powerful these days.
Ai: That only makes it more dangerous. If a master, a wise and experienced man, wields a great weapon, that's beautiful. He can serve peace with it. But if someone's emotions are imbalanced, even if he has the best equipment, he will still mean danger. Modern technology requires calm. You shouldn't trust anyone with a car who has no knowledge about vehicles or roads.
SPIEGEL: So China's political leadership doesn't have its feelings under control?
Ai: The whole system -- not just the political leadership, the military too, the whole power structure, our education system, the whole of society -- is suffering from being cut off from the free flow of information. That's why the country can't face up to open competition -- unless it resorts to measures like North Korea.
SPIEGEL: What's wrong with China's education system? According to the OECD's most recent Pisa study, an international ranking of education systems, students in Shanghai are the world's best in arithmetic, natural sciences and in reading.
Ai: I think our system is hollow and empty. Let's talk about humanity, individualism, imagination and creativity -- those are the values a society is built on. What education are we getting, what dreams do we dream? I deal with students every day -- from China, Germany, the United States, Hong Kong and Taiwan. And I've noticed that the Chinese students are the least trained in having a sense of aesthetics. They lack any ability to sense what is beautiful or what is proper. They can be learned and skillful, but they lack the ability to make their own free judgment. It is really sad to see young adults of 20, 25 years who were never taught to make their own decisions. People who can't do that don't get a sense of responsibility. And if you lack a sense of responsibility, you push the blame onto the system.
SPIEGEL: Why are you put under such manic surveillance? There are more than a dozen cameras around your house.
Ai: There's a unit, I think it's called "Office 608," which follows people with certain categories and degrees of surveillance. I am sure I am in the top one. They don't just tap my telephone, check my computer and install their cameras everywhere -- they're even after me when I'm walking in the park with my son.
SPIEGEL: What do the people who observe you want to find out, what don't they know yet?
Ai: A year ago, I got a bit aggressive and pulled the camera off one of them. I took out the memory card and asked him if he was a police officer. He said "No." Then why are you following me and constantly photographing me? He said, "No, I never did." I said, "OK, go back to your boss and tell him I want to talk to him. And if you keep on following me, then you should be a bit more careful and make sure that I don't notice." I was really curious to see what he had on that memory card.
Ai: I was shocked because he had photographed the restaurant I had eaten in the previous day from all angles: every room, the cash till, the corridor, the entrance from every angle, every table. I asked myself: Gosh, why do they have to go to so much trouble? Then there were photos of my driver, first of him sitting on a park bench, then a portrait from the front, a portrait from the back, his shoes, from the left, from the right, then me again, then my stroller.
SPIEGEL: And he was only one out of several people who follow you?
Ai: Yes. They must have a huge file on me. But when I gave him back the camera, he asked me not to post a photo of his face on the Internet.
SPIEGEL: The person monitoring you asked not to be exposed?
Ai: Yes. He said he had a wife and children, so I fulfilled his wish. Later I went through the photos we had taken years before at the Great Wall -- and there he was again, the same guy. That often happens to me, because I always take so many photos: I keep recognizing my old guards.
SPIEGEL: Is it possible to get used to being watched so closely and permanently?
Ai: The way I do it is very simple: When I counted that they had installed 15 cameras around my house, I decided to install four further cameras inside my home -- one in my bedroom, one at my desk and so on. I thought: If you want to know everything about me, then I'll broadcast and show everything to you. Then I went live with the webcams.
SPIEGEL: Do you consider that to be art or politics?
Ai: Both, I applied their tactics in order to push them into another more philosophical light and to wait and see what happened. It didn't take long for them to call and ask me to please turn off the cameras. I said: "You want to know what I'm doing. Hundreds of thousands of others want to know as well and have been following me for days." It became a big event. They said: "Please turn off the cameras." I asked them if it was a suggestion or an order -- it turned out it was an order. Then I switched them off.
SPIEGEL: The Internet is strictly censored in China, but it is still brimming with ideas and criticism.
Ai: That's why the Internet is the best thing that ever happened to China. It turns us into individuals and also enables us to share our perceptions and feelings. It creates a culture of individualism and exchange even though the real society doesn't promote it. There isn't a single Chinese university that can invite me to give a talk. Even though I know there are many students who would like to hear what I have to say.
SPIEGEL: How do these limitations affect your work?
Ai: It doesn't really affect me because I work and live in the Internet. My virtual life has become my real life. I was reminded of that again a few days ago: I asked my colleagues to print out everything I've written on Twitter in the past three years.
SPIEGEL: Like a book?
Ai: It's around 20 volumes, a pile of paper that reaches up to your hips. I post virtually everything I do on Twitter or Instagram. It's a big art exhibition. Previously a few hundred, perhaps a few thousand people came to my exhibitions. Today I post a video and half a million people watch it.
SPIEGEL: Your government persecutes you and hasn't let you travel abroad for almost three years -- why doesn't it switch off your Twitter account?
Ai: I don't know that there's a clear reason. The relationship between the Chinese government and me is like a Cold War.
