First, cultivate their happy experience. Positive psychologists believe: "Happiness is the subjective positive attitude and feeling that the subject thinks that his current living state is his ideal living state." Although we can't change the living conditions and environment of the left-behind children in family of origin, we can change their views on some things, change their inherent concept of family of origin and give them positive hints.

Through communication with left-behind children in rural areas, teachers can increase their knowledge and understanding of their parents' going out to work, let them express their views on their parents, let them understand their love as much as possible, let them feel their love and enhance their happiness.

Second, cultivate their positive and optimistic emotional experience. Teach them to learn correct attribution and be good at attributing to external factors when encountering difficulties and setbacks; When they succeed through their own efforts, they are good at attributing it to their own efforts rather than relying on luck, and also teach them to learn to find advantages in themselves.

Third, guide them to establish a correct world outlook, outlook on life and values, and set small goals for their study. Finally, cultivate their positive emotional experience. Let them learn to discover beauty, encourage them to write a weekly diary, record the happy things they encounter or experience every week, record all the beautiful things they find, and improve their mental health.

Fourth, cultivate your ability to resist setbacks. Mental health educators should make them fully aware of setbacks, learn to use positive psychological hints when encountering setbacks, and solve them with a positive attitude. Secondly, enhance their self-esteem awareness. Mental health educators or subject teachers respect students in class and life, tap the bright spots in children, cultivate them, and make children realize that they are a complete person and a valuable person.
