Last Saturday I went to the Great Wall with some of my friends.In our way up,we saw many volunteers working in the sun.They helped the elders with their bags,took photo for some tourists and answered people's questions.Because they were very tired,they didn't stop to have a rest.Just at the moment,we saw a little boy standing alone,cried.We went over and asked what is the matter.From his answer we knew he couldn't find her mother.We told him not to worry and then we tried to get in the touch with his mother with the phone number he had given us. Twenty minutes late,his mother turned up,and thanked us again and again.That day we enjoyed the beauty of the Great Wall,and felt the warm of the society.If everyone can reach out helping to others,the world will be more harmonious.
