On the way to Mt. Sorak, we happened to have a great view out of the door from the bus we took. It was Hanjiang and also called Green Hanjiang. I knew it at history class when I was a junior high school student. How vivid it was, it was just in front of my eyes and I never thought I would get a chance to meet him (Hanjiang) personally. Um..., let me think what Hanjian is: It's one of the biggest stream tributary to the Yangtze River and it's 1577 kilometer long. However, due to Hanjiang goes across China and Korea, it's 514 kilometer long in South Korea.
