The Korean traditional house from the Joseon Dynasty is called a 'hanok'. It's built by natural materials and it's separated by 'sarangchae' for men 'anchae' for women 'byeolchae' for unmarried daughters and 'haengnangchae' for servants. The kitchen was near 'anchae 'and 'byeolchae' because only females cooked food in noble mens' house. Moreover, most noble men

 had 'family shrines' in a good position. There were four tables for four close ancestors. Every day, the eldest male went to the shrine to show respect to their ancestors. All of these things are because of confucian thinking.

In 'hanok', people used 'jangdokdae' and chamber pots. There were jangdokdae in most houses in the Joseon Dynasty. Jangdok are ceramicware used for storing food. They are good at fermenting food because there are small holes in the sides. 'Chamber pot' is for urine. Bathrooms were far from the house so people required chamber pots in the Joseon Dynasty.

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

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

Great work and explanations.
