In my case, I was stuck there for quite a while. New York is large enough to be a very abstract city, so nobody cares.

The United States is a melting pot. Like John F. Kennedy said, it's a nation of immigrants. But Donald Trump wants to build a fence that clearly makes the statement: "You and I are divided. We're different, and you're dangerous." That kind of thinking stops human, civilized evolution. It's dangerous to create that kind of tension.

Historically, China is not a nation of sportsmen. We traditionally put more emphasis on being close to nature than pushing endlessly to excel. A philosophy that values tranquil contemplation of the landscape cannot easily be adapted to the Olympic slogan of 'higher, stronger, faster.'

Now many enterprises are made by individuals, so the attitude has started to change.

I have to find a place for my own. I have to search for my own happiness.

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.
