China and the U.S. are two societies with very different attitudes towards opinion and criticism. In China, I am constantly under surveillance. Even my slightest, most innocuous move can - and often is - censored by Chinese authorities.

Expressing oneself is like a drug. I'm so addicted to it.

It is not an easy job to govern China, I am aware of that. There are crises and emergencies all the time, we might not even be aware of some. But I am afraid we'll have to wait and observe precisely what the government is up to.

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.

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.

We live in changing times, and many people experience the challenges that come with it. In the face of uncertain futures, no one will know what to expect.

The leadership knows that you cannot solve the issues of China's future with the means of the past. The demographic consequences of the one-child policy, the build-up of the welfare state, the jobs for 7 million university graduates every year, the immense corruption: Even some Western governments would have to scramble to find solutions to such problems.
