Parents should encourage their children to find money because they are doing the right thing. Parents should teach their children, who to give the money to, and how to confirm whether it is the owner. At the very least, the child should check the amount with the person who wants money. Of course, the society is too chaotic, and sometimes they may be beaten. At this time, the best way is, as the song goes, to give it to the police uncle or to the parents.
