Because people along the route had realized that there was demand and quickly organized supply. That's so Chinese. In a well-organized country like Germany, such a problem may not have arisen in the first place, but in China people immediately recognized an opportunity.

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

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.

China's economy became more complex. By now there is a large number of small- and medium-sized companies that work quite differently from big, state-owned enterprises. They don't follow any long-term business plan and don't rent office space for years to come. They start out and need an office right away, for a week, a month or half a year, and they want to be among other entrepreneurs like themselves.

I have a profound dislike for showing off one's material wealth. This is insensitive and it is not what human hearts are made for. But what I like about China and sometimes miss in Europe is the entrepreneurial spirit of our young people, their ambition and dynamism.

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.
