The history of the market goes back to the Shilla Dynasty. The marketplace in the Chosun Dynasty first opened in Seoul in the 15th century and following the usage of the currency, the number of market sites surged to 1,000. By the end of the 19th century, the number of the market increased to around 1,600. As the marketplace was set up every five days, people exchanged farm products from the farming community for artifacts from craftsman.

In addition, the marketplace also served as a place to promote new cultures and exchange information
