Eating raw or undercooked food in mainland China is just asking for trouble. Sorry you went through that - I hope you don't get an anti-sushi mindblock and can enjoy real, quality sushi again.

It's best to never eat raw or undercooked food in mainland China or any other developing country...regardless of what you see people on the Travel Channel and Food Network doing. I'm sure Bourdain and Zimmern have suffered through plenty of nights like yours after the cameras are off.
