What is "oncheon-cheon"

Oncheon-cheon (also known as the Oncheon Stream or Oncheon River) is a tributary of the Suyeong River in Busan, South Korea. It was previously known as the Seocheon or Dongnaecheon. The source of the river is on Geumjeongsan. It then flows through the built-up area of Busan, passing between Allak-dong ( Dongnae District) and Yeonsan-dong ( Yeonje District) along the way.

In 2003, the Busan municipal government began redevelopment in order to address the stream's environmental issues and provide recreation facilities on its banks. The Oncheon Stream Park along the banks of the river is an excellent place to view the blossoming of cherry trees.
