How about working as a female security guard in the Forbidden City at the age of 27?

It is not good to be a female security guard in the Forbidden City at the age of 27. It is definitely not good for girls to be security guards, because girls' physical conditions are preferred. Born weaker than boys, and being a security guard requires a certain physical strength or weakness. If you are a girl, you must protect your own safety first. Sometimes girls can't even protect themselves. How do they protect others? So I suggest you change your job.
