Qingxi River is a river in the center of Seoul, South Korea. You should have heard the story of Qingxi River. In order to develop the economy, Qingxi River was covered with underground canals. The water quality of Qingxi River became bad because of the discharge of wastewater. Later, it was treated and became what it is today. Qingxi River is not far from Jingfu Palace and Qingwatai. If you have finished browsing over there, you can come to Qingxi River and play with it, but the night scenery is still beautiful here. I recommend evening.
