Other provinces and cities besides yourself. For example, in Jiangxi Province, there are 22 other provinces and cities except Jiangxi Province. They are all from other provinces. Working in another province means that he works in another province, not your province. Working in other provinces, he may also cross several provinces and cities, the final result, so other provinces do not necessarily refer to a province. But in the abstract, it is a specific province among all other provinces except itself.
