Tolong jelaskan mengenai Gu ("District"; 구; ) dari Babagian administratif Koréa Kidul dalam bahasa sunda

Séoul, the metropolitan cities of Gwangju and Daejéon and the cities of Suwon, Chéongju, Yongin, Pohang, Ansan, Anyang, Goyang, Séongnam, and Jéonju are divided into "gu"s, but do not have any "gun"s, whereas the metropolitan cities of Busan, Daegu, Incheon and Ulsan are divided into "gu" and also have "gun". "Gu"s are similar to London's or New York's boroughs, and a "gu"'s government handles many of the functions that are handled by city governments in other jurisdictions. "Gu"s in cities such as Cheongju and Jeonju have fewer powers than those of Seoul and the metropolitan cities. "Gu"s are divided into neighbourhoods ("dong").
