Sometimes parents and teachers are too strict with children. They always expect too much and put pressure on them to become better and better. And adults insult their children when they get angry. Words can be weapons that are very harmful to children's development. Like invisible knives, adults stab these words into their children's brains, causing psychological problems such as depression, autism, violent tendencies, aggressive behavior, etc. These posters call on parents and teachers to pay more attention to how they communicate with children and to educational methods and environment.
