Dong River is the last remaining river of mysterious beauty in South Korea.
The streams from the steep valleys of Jungsun, Pyoungchang -- Ohdaechun, Gojichun, Imgaechun, and Songchun
-- form Joyang River in the town of Jungsun.
And from the point where Joyang River meets with the stream of
Dongnamchun, the 51km-long river is called Dong River (Dong Gang).
This river meets with Seo River (Seo Gang)
in Yongwol, which flows to become the Nam Han Gang, the South Han River.
Nam Han Gang flows past Yeo-ju, and Seoul, ending its journey in the Yellow Sea.
