Layover in Shanghai
On my way to Tokyo, I had a 7 hour layover at Pudong International Airport. I went outside the airport to explore Shanghai for a few hours. I took the fastest train in the world–the Shanghai Maglev (430km/h top speed)–down to Longyang Road Station and then took another train to the city center. Walked around, saw the city center from The Bund, had something to eat, and went right back to the airport. 10/10 would recommend.
