99% of the tourism in China is domestic. Foreigner shouldn't have white cards on the law because of tourism, that's arrogant and unhealthy.
I was afraid of China because of these random news. But when I finally went there in September, I was surprised as all the internet fear mongering was wrong. When you read your local newspaper and see a murder, are you afraid to go out ? No because it's an outlier, as is the case above. I went alone for 1 month in China and felt much safer than in France. But if you plan to go to China to play the game of law for money, then except to lose big. That's why the country feel safe, the risks are huge, that means dissuasion. Avoid political talk and don't be arrogant = 0 issues there.
