What is "hyeon"

The hyeon were administrative subdivisions of Korea during the Silla, Goryeo, and Joseon periods. They were typically slightly smaller than today's si and gun (see Subdivisions of South Korea, Subdivisions of North Korea). They were abolished in the Gabo Reform of 1895.

During the Goryeo period, there were about 335 hyeon; during the Joseon period, 164.
