Today, we reviewed the powerpoint about North Korea. And we made a big discussion. Someone was mad because China helped North Korea against US. They are so kids. China didn't really want to help North Korea. But China had to help because if North Korea was taken over, it would be very dangerous for China. Besides, some said they want to throw nuclear bomb to North Korea. I think that's what an angry kid usually do. What I want to say to them is that don't bring emotion with you when you talk about history. History should be talked in a completely objective view. Don't take governments' false as personal false.
