What does the chemist of entry-exit inspection and quarantine bureau do?

He is a contract worker in the technical center, mainly doing some auxiliary laboratory work. There are also a few high-level contract workers who do an analysis independently. The salary of the technical center is definitely different from that of other formal staff, which is about half lower and the future is far from perfect. But if you are flexible and sociable, you can establish a certain personal relationship in the inspection and quarantine bureau. It is also possible that a very small number of business experts have the opportunity to be admitted to the formal career establishment after making enough contributions, but there are few opportunities.
