"Suhomlinski's educational thought is full of his love for students and humanitarian spirit. He believes that the core task of the school is to cultivate qualified citizens and happy individuals with all-round and harmonious development, so that students can develop harmoniously in five aspects: moral education, intellectual education, physical education, labor and aesthetic education.

Suhomlinski attaches great importance to the educational role of role models. He said that without the shining example of his father, all the remarks about children's self-education would become empty talk. "As far as harmonious education is concerned, it is very important for United and friendly parents to influence their children together. The love, friendship and mutual support between father and mother is an intuitive example for children to introduce into the complex field of interpersonal relationships.

In a family where parents love each other, children will also become "friendly and sincere". "They consciously try not to bring sadness, anxiety and sorrow to their parents." This is precisely the result of "father and mother's serious mutual concern, mutual loyalty and consideration".
