If you have been to Seoul, you must have heard of Insadong. If you are about to go to Seoul, don't miss a visit to Insadong. It's a must-see place for many foreigners after they come to Seoul. Just like the saying "he who does not reach the Great Wall is not a true man" in China. Insadong not only carries thousands of years of traditional Korean culture, but is also an important resource for many overseas scholars to study Korean history and culture.
