Today, I went to national museum of korea. I learned many things. First, During the Ice age human beings began to walk upright and started communicate. People lives in caves. And some day, people think makes tools are good at hunting animals. People began to use Hand Axe to hunt animals. But they have to move because there is no more food to eat! It is called paleothic period.

  When Neolithic period, they became settled in one place.Because they started farming. And when paleothic period, they use chipped stone, but when Neolithic period, they use polished stone.

  During the bronze Age, they have a levels. So when leaders of tribes died, they have to show there influence and power. So they made dolmens.

  After bronze age, there is the first country in our history. It is Gojoseon. There are story about Gojoseon. A long time ago, there were  tiger and bear. Tiger and bear went to Hwanung and said "I  want to be a human." So Hwanung said eat garlic and mugwort for 100 days in cave." Tiger gave up and ran away. But bear became Ungnyeo. Ungnyeo and Hwanung married.

  After Gojoseon was destory, there were Goguryeo which established by Jumong, Baekje which established by Onjo, shilla which established by Park hyeok geo se.

  Shilla unified three country and Daejoyoung who was Goguryeo person established Balhae.
