Korean traditional house in Chosun Dynasty is called 'Hanok'. It's built by natural materials and it's seperated by 'sarangchae' for men 'anchae' for women 'bealchae' for unmarried daughters and 'hanglangchae' for servants. Kitchen is near 'anchae 'and 'bealchae' because only females cooked food in noble men's house. Moreover, most noble man

 has 'family shirne' in a good position. There are four tables for four close ancestors. Every day, eldest male went shrine to show respect to ancestors. All of these things are because of confusian thoughts.

In 'hanok', people used 'Jangdokdae' and chamber pot. There are Jangdokdae in most houses in Chosun Dynasty. It's ceramic ware used for storing food. It's good at fermenting food because there are small holes in the wall. 'Chamber pot' is for urine becuase of neatness problem. Bathroom was far from the house so people required chamber pot in Chosun Dynasty.

Also, our ancestors used 'Ondol' to keep floor warm. Koreans needed ondol because they usually sleep on the floor. Cooking fire in the kitchen warm the air and heat the floor.

I think our ancestors are very bright and creative becuase they made useful object to make their lives comfortable.
