The best, the worst and also the most distant place I have ever visited is China. I was there 2 years ago.
What was the best? The best were the little and the extreme differences between their country and Europe. They not only live and think differently, but they even look completely different. People in China tend to be minute, there are fewer animals and children seem to be lonelier, because China enforces a one-child policy. The Chinese are more polite than Czechs; there is less differentiation between the rich and the poor: poor people can live next to the rich. Even driving a car is something incredible. It is more like a rollercoaster ride! The Chinese are also very good at mass production of consumer goods: you can buy a Dior handbag for around 200 Czech crowns, an iPhone for about 500 Czech crowns and… in fact, you can buy practically anything at such low prices, which is really amazing for the customer, but not so much for the brand names, I guess.
