It is called in Korea as Oiljang (Five-Day) Markets where Korean people would traditionally go to pick up day-to-day items, such as clothing, agricultural and marine products, and many more and enjoy traditional delicious foods. Oiljang Markets are held every 5 days and are full of lots of exciting activities and scenes.

An example of a Five-Day Market is Jeongseon 5-day Market where products like Gochu (Korean red peppers), garlic, herbal medicine, vegetables, corn rice wine, buckwheat paste, and more are sold. Gangwon-do's Jeongseon 5-Day Market is the place to go to if you would like to buy mountain herbs. The generosity of the market's citizens can be felt while exploring the grounds for its famous wild greens during spring, and medicinal herbs in the autumn. Jeongseon Market's specially featured product is the Goraengji, a vegetable that grows in mountainous regions or on plateaus at 500~700m above sea level. There are also many unique dishes in Gangwon-do that will catch your eye or whet your appetite. One delectable item is a dish made with buckwheat noodles called Kotdeungchigi (hit the nose), because people would pull on the noodles too hard when eating and "get hit in the nose". In order to experience the full atmosphere of the country market, you must try drinking a bowl of corn Makgeolli (a variety of Korean wine), a specialty of Gangwon-do, and eating a bowl of Kotdeungchigi noodles while sitting on a mat.
