Hello

My name is Jack.

I went to Changdeok Palace.

I'd like to introduce about Don-hwa mun.

Don-hwa mun was built in 1412.

It is a two- story pavilion.

It looks very giant, and beautiful.

There is a drum on the second floor.

A nine ton bell was hung with huge drum on the second floor of the gate. I wanted to see it. However, I couldn't see it. It struck 33 times at 4a.m. It meant opening the world. The bell might wake up all of the people intheHanyang.  

The bell was rung 28 times at 10p.m. It was expectance of peaceful night. The bell must be an alarm at that time. In those days, they didn't have clocks. The drum and bell were  good tools to communicate with the people. My school has a bell. It allows us to know when to start and finish classes.

I like those ideas so much. I want to be a scientist. I will make  good things to help people make  easier lives.
