I went to Amsadong last saturday.

Before I arrived  at Amsaprehistoric site, I thought prehistoric people are silly and fool like monkey.But after I tour there, I fix my thought. Now I will explain about prehistoric periods, and relics.

There are 4 different periods.Old stone age, New stone age,Bronze period and Iron period.

In stone period, people used stones to make tools for breaking and grinding, And they started agriculture in New stone age. To store crops and meat, they made comb-patterned pottery. In bronze period, It started to appear powerful leader throughout wars and make Dolmens for powerful leaders' tomb. The most impressive relic is Bronze dagger to show the power of leader.

Lastly, in Iron period, they used iron to make tools like axe.

There are many impressive relics including the relics I explained.

After I tour the site, I think our ancesters are very smart and wise.

I want to follow them!
