I’m very worried: I just came to Shenzhen to work and I don’t have many acquaintances. I’m single, so I can only go shopping and go to the park alone during breaks or at night.

Shenzhen is a mixed bag! I stayed there for a few years, and this has something to do with the way you dress. To be honest, if it was you in the photo, your appearance and figure really don't fit that outfit. It is easy for some people who are not doing their job to misunderstand you. It is recommended that you go out less often if you are alone at night, as it is not safe. Try to bring a companion or two with you when you go out.
