Just spent a week in Shanghai and it was truly an amazing city. You can see the tallest hotel and fastest train the world next to traditional residential area where they still share the bathroom and kitchen. Which is the real Shanghai? My impression of the city is crowded, chaotic, wealthy and energetic. My quality of life in Shanghai has massively increased as I can take a taxi everywhere (around £2-3), can go into a restaurant without seeing the price of the menu and can have a massage everyday (only £4 per hour). There are lots of opportunities for entrepreneurs and Chinese who educated abroad. For me? I will go wherever is best for my family.
