One good turn deserves another.It is well known that man knows feelings.People live in harmony of peace.People know who to help because they think they will deserve what they do though not all of them...在長一點In China many people help others without any deserving. There are quite a lot of volunteers like Guo MIngyi. He is modern Lei Feng and saved many,many people in trouble. He saved them by blood transportation. He is so kind to people that we are moved by what he has done.He sets a good example to us.在不采納我就要灰心了。
