I write this about to collapse from exhaustion after a solid 26 hours of airports, airport shuttles and flights, and, alas, no sleep. We’ve made it to Pudong Airport in Shanghai, where we await our final flight to Nanjing. We thought we’d sorted out a way to tunnel under the Great Firewall of China to access Facebook, etc. But, a quick check on the airport wifi suggests that the tunnel isn’t working. So, this blog may well be our only regular forum for updates. Not just now, though. First, a much-needed nap in the departure lounge, one final short flight, and then an honest-to-goodness whole night’s sleep in a hotel. Zzzzzz…..
