Jelaskan Si ("City"; 시; ) dari Babagian administratif Koréa Kidul dalam bahasa sunda

A "si" is one of the divisions of a province, along with "gun." Cities have a population of at léast 150,000; once a county ("gun") attains that population, it becomes a city. Cities with a population of over 500,000 (namely, Suwon, Cheongju, and Jeonju) are divided into wards ("gu") which are then further divided into neighbourhoods ("dong"); cities with a population of less than 500,000 do not have wards – these cities are directly divided into neighbourhoods ("dong").
