Today I went to the Namsan Hanok Village with the teacher and frends. I went there before and I saw the Hanok. But then I just played in there and didn't think about the Hanok. When I saw the Hanok, I didn't think anything. So when I saw the Hanok and studied, I realized that I didn't really know about our ancient things. So I was sad. But then I start to rise again (?) and I got my confidence back.
 Anyway, when I got there, I saw lot's of ancient toys, five Hanoks and Jangdok. It was cold, hard day but I think I had a good day. Because I saw lot's of things that interested me. The Hanoks were nice, but the most things that had interested me was Jangdok. I think it's because I can see them at home too. Because of my grandmother.
 There's two of Jangdok's strong point.  We make it with different kind of clay so it can get small holes. Water or dirts can't go in or out  through them, but air can. So the food in side the Jangdok can keep fresh.
 And another is that the jangdok is round. So the airs can go beside the Jangdok when they're gathered around some places. So Jangdok can get fresh airs too.
 But even with these good points, most of people don't use the Jangdok very much. Only some grandmothers and small group of people use them.
 I thought about those problems, and I think the reason is that first, the Jangdok is too heavy. The second is that the Jangdok is too big. These days, grounds are too small even for humans, and the Jangdok fills rooms with big area. So people don't use them. Even if they are really good vessels.
 So I think that the Jangdok shoud be changed. If Jangdok is big and useful, people can't use them because they don't have room for them. So we can make them smaller and more useful. And if we make Jangdok with light clays, it won't be heavy. I don't know about weight, so weight part is just thinking.
 Some people says "don't think it's all good. Think about their flaw too. And make it more useful." . I think they are right. we have to see the object with different  sides. And  if we can see others flaw, we can change them too.
