Today I visited Namsan Hanok Vilage. I was amazed by jars. They are called Jangdock.The Jangdock has tiny holes only fresh air can came in and it was storecd under the cround or at shadowed place,ventilation is very good.When we put some Gimchi in there it came out very delicous. So the Jangdock is useful for every one who wants to ear tasty food.
