"5.25" is the homonym of "I love me", and the promoter's explanation is that only by loving oneself can we love others better. The first standard of mental health is to know yourself, accept yourself, experience the value of your existence, and be optimistic and confident. Only in this way can people get along with others, share, accept, give love and friendship and work with others with trust, friendship, tolerance and respect. The purpose of choosing "5.25" is to make college students easy to remember and pay attention to their mental health. Subsequently, "5.25-College Students' Mental Health Day" was recognized in colleges and universities all over the country, and colleges and universities all over the country used this day to carry out various forms of mental health education activities, and even thought it was "College Students' Mental Health Day".
