High score reward! Can someone familiar with the matter introduce the field tasks of Shanghai Customs?

Customs field work is relatively easy but tiring. The position you are applying for is relatively easy, basically nothing specific. It is said that being on duty 24 hours a day is not for you to work 24 hours a day, but for shifts. According to the manpower situation, you have to change two or three shifts, so you won't be tired, but because of irregular work, it may be more harmful after a long time. See if you like irregular schedules.
