Today is my third day of Mariestory, and I am Getting very comfortable on this program. I decided to try the essay competition until I get any of the prizes.

Today, I am going to talk about the history of Cheosun. Cheosun was established by King Taejo in 1392. The fisrt capital of Cheosun was Gaesung, but King Taejo moved the capital to Han yang, which is seoul in 1394.

Also, Cheosun had a lot of artifacts, and I am going to introduce you the Ja-gyuk- ru.The Ja gyuk ru worked by having water poured into the largest bronze vessel which flowed into the smaller vessels which the flowed into the long water tanks. When the water rose up enough, it caused a marble to roll and hit a bigger ball at the other side. The rolling ball would make the gong, bell, drum working, and even cause the wooden puppet turn around.

I think this is for all today. Thank you very much for listening.
