What is "seohocheon"

The Seohocheon is a river in Suwon, South Korea. It has its source on the southern slopes of Gwanggyosan and flows south, through Cheoncheon-dong, past Dongnam Health College, to Seoho (West Lake), near Hwaseo Station. From there, it continues south and joins the Hwanggujicheon. There is a path alongside much of the length of the stream and this is currently being extended north towards the source.
