China hasn't only existed for one day. Now, the whole nation has become richer and it's become a problem. The problem is universal. The factor is big. Everybody has to rethink the balance of the world and the whole landscape.

The idea to use backpacks came from my visit to Sichuan after the earthquake in May 2008. During the earthquake many schools collapsed. Thousands of young students lost their lives, and you could see bags and study material everywhere. Then you realize individual life, media, and the lives of the students are serving very different purposes. The lives of the students disappeared within the state propaganda, and very soon everybody will forget everything.

When I first got into the first-year study after the Cultural Revolution, got into the same school with this group, I wasn't conscious of the so-called "Fifth Generation." I didn't like that kind of study condition because there's no real, true education there.

I always thought that in modern history Chinese people are like a dish of sand, never really close together. But I think a dish of sand is a good metaphor because we have the Internet. We don't have to be physically united. You can be an individual and have your own set of values but join others in certain struggles. There is nothing more powerful than that.

At the moment about 350,000 students return to China from abroad each year - 350,000 young and educated people. I know about them because they know me and often ask me in the street if they can take a selfie with me. These folks are creative and ironic, and the government can ultimately not control what is going on in their heads.

If Shakespeare were alive today, he might be writing on Twitter.

Any politician who respects China's government should tell it openly what is in his heart. It is disrespectful to keep quiet about such issues - both vis-a-vis the government and the people concerned.
