[citation needed] Under Article 3 of the Local Autonomy Act, a city with a population of less than 500,000 may create administrative subdivisions in the form of dong in its urbanised area and eup or myeon in its rural area, while a city with a population of more than 500,000 may create administrative subdivisions in the form of non-autonomous gu.
Big municipal cities are given the power to subdivide themselves into non-autonomous districts (Korean: 일반구; Hanja: 一般區).

As such, Jeju City does not enjoy special autonomy and only has the same legal powers as the much smaller Seogwipo.
