tambons), which are further subdivided into 145 villages (
mubans). Khun Han itself is a sub-district municipality (
thesaban tambon) and covers parts of
tambons Si and Non Sung. Other sub-district municipalities are Si, Krawan, Non Sung, Kanthrom, and Pho Krasang, each covering the same-named sub-district except those areas belonging to Khun Han municipality. The remaining seven sub-districts each have a
