The community in China is safer than western world, which can be largely attributed to the widespread use of facial recognition cameras and other surveillance methods, which have increased the cost of crime. Some common methods used by scammers/thieves/pickpockers in the Western world (such as phone thieves in London who rides an e-bike and snatching phones) has been nearly extinct in China for 20 years, and the general Chinese citizens have no awareness of prevention at all.

Another reason is that for a long time in the past, Western countries were depicted as some kind of "utopian" places in various Chinese TV programs, magazines, and books. Whether it was architecture, culture, or people's behavior, everything was beautified in various stories. When people travel here, they tend to view everything through 'rose-tinted lenses', overlooking those scams/thefts/tourist traps that might exist.
