In January i was in Shanghai on a wee stopover trip. I took advantage of the visa-free policy where you can get into the country for 72 hours if you have an outbound flight. Amazing city very clean and modern. The subway links he airport to the city very easy. It pissed down with rain mostly
Air China flight was surprisingly great. Modern planes, nice economy seats, loads of room and nice food...
