A sub-prefectural municipality, sub-prefectural city, or vice-prefectural municipality, is an unofficial designation for a type of administrative division of China. A sub-prefectural city is officially considered to be a county-level city, but it has more power de facto because the cadres assigned to its government are one half-level higher in rank than those of an "ordinary" county-level city—though still lower than those of a prefecture-level city.
