There is a story related to Guryongsan. According to the tale, the mountain originally had ten valleys, each dragon in one valley. They had to ascend to the sky, but one was late to ascend and was seen by a person, and couldn't ascend. By the means of good conduct for people, he had to be a stream for people to drink and farm. The stream made people wealthier and happier, which was why this stream was later named ‘Yangjaecheon.' 'Yangjae' is a word written in Chinese characters, which is translated as 'a group of talented people.'
