Understanding and mastering the definition of mental health is of great significance for strengthening and maintaining people's health. People have mastered people's health standards and made self-diagnosis of mental health on this basis. If you find that one or several aspects of your mental state are far from the standard of mental health, you should strengthen psychological exercise in a targeted way to reach the level of mental health. If you find that your mental state seriously deviates from the mental health standards, you should seek medical advice in time, and make early diagnosis and treatment.
