Suhomlinski, an educator in the former Soviet Union, pointed out: "Self-esteem is the most sensitive corner of teenagers, the potential power for students to advance, the driving force for progress, the upward energy and a noble and pure psychological quality." Today, we call for cultivating young people's self-esteem, self-love, self-reliance and self-improvement, and attach importance to their all-round development. The development and cultivation of self-esteem is a very important issue. Self-esteem is not only an important aspect of teenagers' psychological quality, but also affects the development of other qualities of teenagers.
