Today I went to Seoul museum of history. At seoul museum, I saw water clock,and sun clock works by the light of the sun, water clock moves by the water when the water flows into the tube, the marble rolls through the tube the marble moves to the dolls to show the time and hit the bell. Jang-yeong-shil made both of them he was the famous scientist in the Jeoseon dynasty.In costumes, common people wore white clothes, Noble people wore colorful clothes.There were one day common people could wore the Noble man's clothes.It's the wedding day.I wanted to see everything in the museum, but I didn't had enough time.I want to come back here again.
