China reformed its state sector before, in the late 1990s. Tens of millions were laid off at the time. That was scary and we had warnings of social unrest. But it did not happen. Instead, there was a restructuring in our economic system. I am not sure if China will follow a Western playbook in this respect.

Our company has only been active in Beijing and Shanghai, two very market-dominated cities. This was an advantage. Land is purchased here in public auctions, in a transparent way. When you do real estate development outside Beijing and Shanghai it is good to have "guanxi" - good relations within the local government.

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.

It is worthwhile to engage in something that is close to one's heart. I had a scholarship. So if I donate money to give brilliant Chinese students an opportunity to study abroad, then this embodies everything I believe in: education, globalization, social mobility. I am an example of social mobility.

When we started out, we were among the first. Beijing had no and Shanghai had very few large buildings. At that time, it was all about building, building, building - and then selling, selling, selling. We were working like a manufacturer. Soon, however, we realized that land was running out in Beijing and Shanghai. So we started keeping our buildings, and managing and renting them out. We became landowners. That was the second act.

I firmly believe that digitalization has only just begun in China. In addition to the taxi, transport, shopping and hotel businesses, many other industries will follow: education, health care, administration, even the legal branch - everything, really. There is still a lot of opportunity in China for the inventive and ambitious ones.
