Brave heart
There was a man in Shanghai,named Yangjia,had a great brave heart i think.Why say so? Course he killed 6 policemen at a time by himself.What great move he did. Everyone konws that our policemen are very strong and they are fierce to people.Every time when we meet policeman we may feel nervous and afraid though they are not as great as what they look like.But he, Yangjia, a man with great brave heart, raised up his knife and cut down and then six policemen over.
No matter what he had done was right or not, no one could disagree that he is a great man with brave heart. Of course, we shouldn't learn to do what he did,but we should learn him to have a brave heart.
That brave heart had gone, but we will never forget it.
