In Hong Kong during the British Hong Kong era, if a policeman was transferred to be a marine policeman, was it equal to being assigned to the frontier (marginalized)?

During the Hong Kong-British period, a policeman was transferred to the Marine Police, which meant being assigned to the front line. The maritime policeman is going to guard the pond. The workload of marine police personnel has been reduced and they are more leisure. He often deals with villagers or fishermen, answers the phone when he is on duty, and often receives missing chickens, ducks and geese from three aunts and six grandmothers. If there are mainland tourists smuggling, it is a major case and should be notified to the superior.
