Today I went to the war memorial of korea.

 From Gojoseon to korea, we have fighted many war.
 In Sal-su war, I learned you can use ideas to win the battle, and less of blood. and when the mongols attacked Goryeo, if the ruling class of Goryeo didn't ran away, we colud have win the war with the mongols. In the Imjin war, I'm surprised by the tenacity, and courage.
 But, the war is crule and it gaves not only bad to the other country, it is bad for our country too. way people have to war? if their was no army in the world, and all the men could work hard. and its good to himself and the his country. then, the people have to don't die in the war and it could be peaceful all the time. if they want to conquer lands, but what is good for him? his country's land is larger? and what is good to have many land??? I want not to fight with the north korea. We have lot about to think about a war.
