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.

No economy, no company, in fact no individual can develop its full potential today without embracing two fundamental trends - globalization and digitalization. They will dominate for quite some time to come.

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.

Many Chinese entrepreneurs are now donating for education; others support foundations in health care and research. None of us wants to be the richest guy in the cemetery.

We have become so quick and effective in building things today. It would be easy to build another Pyramid of Giza or another Great Wall. But these buildings haven't withstood the test of time because of their building quality. They stand tall because they have a symbolic value, they represent a culture.

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.

Growth will be slower, no one denies that. But the question is: Where are the chances and opportunities now? I see some positive and some negative trends.
