What I learned about WWⅠ.

I didn't know anything about the World War I, because I'm not interesting in wars. Wars are cruelty, and people die. I do not like to think about people dying.


Today, I learned that Japan was in it. 9,000,000 people died in the world. Gas effects people's death a little. And there ware a lot of causes to death except battle, for example, lice, rats, and so on.

Many countries joined the war, and it was the biggest war ever.
