I majored in chemistry. What kind of civil servants can I apply for?

There are many others: Customs (depending on the work needs), Inspection and Quarantine Bureau, Nuclear and Radiation Safety Supervision Station, China National Intellectual Property Administration Chemical Invention Examination Department (including Patent Office and Patent Reexamination Board) and so on. Chemical industry must be a big industry, and it must be managed by a corresponding official system, which naturally requires professionals. It's best to see if there are any suitable positions when applying for the exam. After all, not every position needs to be recruited every year, and sometimes it depends on luck. There is also a position that can be applied for without any major.
