According to folktales, in the olden days there was a swamp known as Nong Anggeh located between the river and Nong Anggeh Hill. The condition of this swamp was bumpy and difficult for pedestrians to pass through. This swamp is also the only main road leading to the opposite village. Since there was no other road at that time, the villagers had to go through that road. When they go through the swamp while carrying their children then they have to support or mean to carry their children on their shoulders. The conditions and processing caused this area to be called 'kukong'. Over time this call remained until today and was referred to as 'Kampung Ukong'.
