Ui-dong

Ui-dong is a dong, neighbourhood of Gangbuk-gu in Seoul, South Korea. From June 30 of 2008, Former Suyu-4 dong is changed to the administrative dong. Thus Ui-dong can be called either legal dong or administrative dong.

Etymology
Uido-dong is named after the geographical features of the area, where the tributary of the Han River, called Soguinai, flows through a valley, resembling the shape of a cow's ear. This area is also known for the peaks of Baegundae and Insubong in Bukhansan, which resemble the ears of a cow.
