However, the constitution does allow for some cities, which "are" a constitutionally guaranteed level of administration, to be "prefecture-level" (in the sense that they can take surrounding counties under them), though the original intention was likely to have just a few very large cities in each province be prefecture-level cities that govern only the counties in their immediate suburbs. The rest of each province would still consist of counties under unofficial prefectures. (This was, in fact, the general situation before the 90's.)
