In which country will you find the county-level city Gaozhou and the Jiangdu District which was formerly a county-level city?
Jiangdu District Jiangdu District () is one of three districts of Yangzhou, Jiangsu province, China. It was a county-level city under the administration of Yangzhou until November 2011, when it was converted into a district.
Sub-prefecture-level city A sub-prefecture-level municipality (, pinyin: fùdìjíshì), sub-prefecture-level city, or vice-prefecture-level municipality, is an unofficial designation for a type of administrative division of China. A sub-prefecture-level 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.
