When you are in Shanghai Nanjin Street, try not to respond to girls (usually work in pairs) when they approach you for time or direction etc. They will usually ask you to buy them drink nearby after you've responded to their asking for time or direction. You will be brought to their "pre-selected" cafe and ended up paying 10 to 20 times for common drinks.

Also, when you are in or around major city train stations, make sure you don't look "too blur" or "too curious". You will be targetted and it is not uncommon to see day-light robbery (thief snatching gold chain etc), let alone having your pocket and wallet being picked.
