In the nearly two decades of children and adolescents psychological and mental health work, often see some delayed diagnosis and intervention of the child, and see the parents in the understanding of children’s mental health there are often some misunderstandings: (1) emphasis on wisdom and light ability to make their own bitter wine: some parents only focus on academic performance, mistakenly believe that children learn well enough; a day from morning to night only require children to “learn, learn, learn again” and think “points, points, points, students’ lifeblood”; but do not pay attention to children’s comprehensive quality training, sound psychological development and social adaptability. “Learning, learning, learning again,” the one-dimensional view of “points, points, points, students’ lifeblood”; but do not pay attention to the children’s comprehensive quality training, the soundness of the psychological development and social adaptability of the high and low, for the beginning of the psychological problems of the end of the parents did not pay enough attention to, that good learning can replace everything, leading to the development of the children’s psychological problems. The parents do not pay enough attention to the first signs of psychological problems, and think that good learning can replace everything, which leads to “good students” being at a loss when they enter the society, and even exposing psychological problems during the period of university and study abroad, and performing regrettable cases such as “Lu Gang” and “Liu Haiyang”. Liu Haiyang” and other deplorable tragedies. (2) Poor knowledge and insufficient attention: Parents lack knowledge of children’s mental health, believing that certain behavioral and emotional disorders in children are just a result of children’s ignorance and naughtiness, or that certain manifestations can be cured when children grow up, and failing to put mental disorders on the intervention agenda. Indeed, some children’s mental illnesses, such as attention deficit hyperactivity disorder (ADHD), with age, the development of the nervous system gradually tends to be sound, and some symptoms of hyperactivity will be reduced or even disappeared; however, inattention and impulsive behaviors will be carried over into adulthood, which will seriously affect their academic performance and social adaptability, and hyperactivity will lead to the negative attitudes of the parents and teachers towards the child, which can affect the child’s psychological development and the formation of his or her personality. The negative attitudes of parents and teachers toward the child due to hyperactivity can affect the child’s psychological development and the formation of his or her personality. Some scholars have found that the socioeconomic status of children with attention deficit hyperactivity disorder in adulthood is relatively lower than that of those without a history of ADHD. (3) Losing sight of the other is not worth the loss: Parents have realized that their children have psychological problems, but they are afraid of being looked down upon by others, and they do not choose to consult a department specializing in children’s mental health for fear of their “reputation”. In fact, mental illnesses and physical illnesses should be treated equally, both have their biological basis, and should be treated according to different body systems to see a specialist. Only after diagnosis by a specialist can we distinguish whether it is a normal emotional reaction, a mild psychological problem, or a serious mental illness, and only through professional treatment with a clear diagnosis can we curb the progression of the disease. In particular, the child and adolescent mental health profession has a limited number of doctors nationwide, and should be chosen carefully. Often encountered children after several twists and turns in vain, gradually appeared a number of accompanying symptoms, the condition is getting more and more serious; therefore, to see the doctor to specialize in medical treatment, otherwise ultimately misuse of the condition. (4) Lack of communication, each with his own opinion: the child spends most of his time in school, the teacher’s observation and help is indispensable, frank communication with the teacher to work together, in order to make the child a more conducive to its development of the environment. This also requires a great deal of love and scientific health concepts from the teacher: two parents reflected that the teacher “kindly” prevented the child from going to the doctor when the parents thought they were wondering if the child was sick, and that the child would be better off when he or she was older; although some of the manifestations may disappear as the child grows older, the psychological development of the child is greatly affected during the course of the illness. Although some manifestations may disappear with age, the child’s psychological development is greatly affected in the course of the illness. Teachers should think of the child holistically and in the long term. Therefore, only through communication and cooperation between parents, teachers and doctors can children develop normally and fully. (5) Rooted in the parents, family disharmony: Parents work under great pressure, and when they return home, they relax too much in front of their children, and some of their bad habits are displayed, and the children learn some bad behaviors through their ears and eyes. In addition, parents work nervous, can not find the problem in time, not to mention will not take the child to the doctor in a timely manner, delaying the child’s treatment time. In addition, the husband and wife do not get along well, the family environment is bad, resulting in children and teenagers psychological development is not sound, and even very young children will have emotional and behavioral problems. Even if the child represses the childhood psychological conflict, as an adult, the seed is likely to breed undesirable branches in a certain situation. Some scholars research specified: ADHD children’s family intimacy, emotional expression, knowledge, success is lower than normal children’s families, while the family conflict is high. (6) Avoiding the important and losing the important: Parents are overly concerned about the side effects of medication and are reluctant to take medication. However, the consequence of not taking medication is delayed condition, which affects the psychological development of children and adolescents. The consequences are much greater than those caused by the side effects of drugs. This should be viewed in the context of the doctor’s opinion. There was a child with Tourette’s syndrome, after taking medication to improve the secret to the Chinese medicine treatment, half a year later, the disease rekindled, for fear of being blamed by the doctor, it has been bouncing around to other institutions for treatment, the condition is getting worse and worse, and finally appeared to self-injury and self-mutilation symptoms before coming to the doctor again, but, at this time, has become a refractory condition. All these factors will affect the handling of children and adolescents’ problems, thus affecting their normal growth. Thus, it is wise for parents to take a comprehensive, macro, long-term and scientific view of children’s psychological problems. At the same time, the healthy growth of children and adolescents psychological only get the attention of the whole society, can really improve the quality of the population of the next generation. Let us together, common concern for children and teenagers mental health!
