Six weeks staying in China means nothing. China is already the 2nd largest economy but it still develops at an unprecedented rate. Urbanization in the country only reach 60% and will increase to 90% in 2030. 'Ghost cities' and empty malls will be filled very quickly in the next 3-5 years. There's actually a shortage of malls/supermarkets/schools in most communities in China, and that's the reason why e-commerce prevails and companies like Alibaba are reinventing retail.
> So pretty much everything I read about China's economic development, I don't believe.
You shouldn't, especially if you only read reports from Western sources, which are heavily biased and often telling only what people prefer to hear. People in the States are either ignorant on what's going in China, or so entitled to think there's only one way for how societies work.
