A real treat for treasure hunt lovers, and it's quite a unique one. At the Korean Cultural Center's flea market (between midday and 3 pm), you can give away clothes or exchange them with others. The fun part starts with the payment: you can only use replicas of the traditional Korean brass coin, yeopjeon (엽전). Vendors will automatically get the coins according to the quantity and quality of their goods, while other participants can earn them through experiential activities. The event is open to everyone who loves Korean culture and flea markets, entry is free, but registration is needed.
