Li Mei went to the cinema on last Sunday. On the way there, he saw two boys climb up the back of a truck, so he hurried to ask him to come down from the truck. The two boys came down and Li Wei told them that it was dangerous climb up the truck like that. The two boys said that they have done something wrong but their faces went red.

Yet, after a while Li Wei was very surprising to see the children were running after a tricycle with many thing on it. Soon they caught up with the tricycle and pushed it hardly. Li Wei ran to join them in helping a driver.
