Felix, sorry to hear about that! Another bullet to add to your list: at every checkpoint into Shanghai that I have ever ridden through, there is ALWAYS a path through a small village that bypasses it. Every time I have taken a ride outside of Shanghai, be it to Taicang, Jiangsu or the 5 day tour of Zhejiang, we have left and comeback through one of these. I ride with a group of Chinese riders, many of whom ride bikes that have the fake license plates so doing this is a necessity. If you can familiarize yourself with these, it's no fuss!
