Today I went to the Namsan hanok village.

I saw many things,but the 'heating sytem' was the best for me.Heating system is english of ¿Âµ¹.

It's function is that the women make fire in the fire hole,and the heat follow the road made of rock.

The heat pass the rock and the rock got hot.

The heat go to the wood and the wooden floor got warm.

The heat go all over the house and the smoke go outof the chimny.

Mans stay in the room and childrens stay closer because It is cold outside on winter.

Heating system is used on winter.

I think our ancestor are smart because they can make things for there life.
