When we started out, we didn't really think that the era of great opportunity would end one day. We were much too busy developing our companies. But in today's China you can build a city, even a mega-city like Beijing or Shanghai, within 10 or 15 years. And then you are done. So in real estate development, the Gründerzeit is over. But that is not the case in other sectors.

Isolation means a lack of growth. I grew up in China at a time when the country was completely isolated. That era is over.

The question is not about whether it will work or not. It's how quickly we can pull it off. Structural change will happen. When economies grow, there comes a time when you cannot rely on investment alone. We had that. The return on investment is becoming less and less. So we have to change. The old model doesn't work anymore. It's a question of speed.

But the higher our standard of living, the higher our levels of education, the further people will look around. And we can see which level of openness other societies enjoy. We are no different - we too want more freedom. The question is: How much freedom will be allowed?

Mark Zuckerberg recently announced that he will donate $45 billion of his wealth to philanthropy. Two years ago, my husband and I decided to endow $100 million to set up the SOHO China Scholars. This program will give financial aid to Chinese students so they can attend the best universities in the world.

I'm afraid what we are building today will not have the same impact and sustainability of the architecture of a 100, 500 or 1,000 years ago. The buildings of those days were miracles. We don't perform such miracles today. So we should be a little more modest. For my part, I'll be glad to show one of my buildings one day to my grandchildren and say: I'm proud of that.
