The word mental health is put forward by people in the process of understanding and dealing with psychological obstacles. In the early days, in some countries, all eccentric people were regarded as aliens, treated inhumanely, some were handcuffed, and some were exhibited as exhibits on weekends. Especially when socialism changes or natural and man-made disasters occur, the suspicion, contempt, hatred and persecution of aliens will intensify. With the emergence and development of psychological science, people's views on aliens have gradually changed, and it is found that these eccentric people can be treated, so various institutions specializing in accommodating aliens have emerged, and treatment has replaced punishment. However, most of the treatment institutions at that time were located in monasteries, and their methods were only based on providing sunshine, air, freedom and biological needs for these people. It is in this medical process that people find that the psychological activities of these eccentric people are a major cause of mental discomfort and behavioral heresy, and these psychological activities that cause obstacles sometimes appear in normal people and even doctors, such as anxiety, tension, depression and so on. This shows that it is important for everyone to correctly understand and evaluate themselves.
