Paranoid character children’s main performance in the following aspects: 1, sensitive character, suspicious: for example, often do not believe in what others say, or doubt around the loyalty and credibility of the children to their own, on what others think is right or what others have done is always skeptical; 2, stubbornness: only think what they say, do the right thing, for example, they do the question must be correct, even if others do the right thing, in the case of consistency with their own answers, must determine that others are wrong rather than wrong. For example, they only think that what they say or do is correct, and even if others do it right, they will surely think that others are wrong instead of themselves if they don’t agree with their own answers. In this case, the child’s character development may go to the extreme, some children are too conceited, always think that they are the best, the strongest, no one can surpass them. Once someone surpasses him or her, the child will find it difficult to accept or consider it abnormal; some children may have extremely low self-esteem, lack confidence in themselves, and believe that what they do or say is wrong; some children may also have social disorders, and have varying degrees of difficulties in communicating and interacting with children.
