fact, on many occasions he would even receive the spirits who managed to track him down as guests in his home. After a short period of entertaining them, he was able to send them on their way without even so much as a struggle. So skilled was he at persuasion, that in no time he had the spirits believing they had mistaken him for someone else. They would then go off again searching, never the wiser as to this man's true identity. One spirit, who was determined to be fooled no longer, thought about the problem seriously. After deep contemplation, he came up with a cunning plan that would surely allow him to capture Dong Bangsak once and for all. As it happened, Dong Bangsak was one day passing over the Tancheon. There, he came upon someone washing clothes in the stream water with a piece of charcoal. It was the spirit disguised as a human. Unable to resist this unusual sight, Dong Bang-sak asked, “Why are you using that charcoal to wash your clothes?” The spirit replied, “Because charcoal gets them whiter, of course!” Upon hearing this, Dong Bangsak burst out into a ferocious laughter and said, “Ha! My boy, I have lived 180 millennia, but never have I heard of someone making clothes whiter by washing them with charcoal!” With this slip of the tongue, the illusive Dong Bangsak had given himself away. The spirit at once knew that he had at long last found the man whom he had been looking for. He then quickly apprehended Dong Bangsak and took him to the underworld, bringing to a close the life of this long lived man of wit and deception. From this, though, we have the name for this well-known stream, the Tancheon: The Stream of Charcoal. Water parks Along the approximately 25-kilometre stretch of the Tancheon that passes through Seongnam, there are five water parks open to the public. They are free of charge and popular with families with young children. The Tancheon water parks (탄천 물놀이장) are open every year from July 1 to August 31, from 10 a.m. to 8 p.m. At the parks there are changing rooms available as well as many chairs and picnic tables.
