As we all know, family education is the initial stage and key stage in people's life-long growth education. Especially for children, family education plays an important role in shaping their personality, cognitive development and social development. The famous educator Geer put forward: "The appearance of father is a unique existence with special power to cultivate children." Everything a father says and does will have a far-reaching impact on all aspects of his children.

According to the theory of father's role, father plays the basic role of playmate in the process of children's growth, and his parenting behavior is to play with children. For the simplest example, in the process of raising a child, the mother usually holds the child in her arms, so that the child can feel the warmth of her mother and even hear her heartbeat. Fathers usually hold their children high, or put them on their shoulders, so that they can see farther and see more objects, and their vision is another world.

By operating and exploring various game activities, the father makes the children get rid of their dependence on their mothers and stimulates their curiosity and thirst for knowledge. Successful exploration experience can cultivate children's self-confidence and enhance their adaptability to unfamiliar environments.

In 2000, it was pointed out that the relationship between father and children is more based on games, and the lack of father's role directly leads to the lack of children's game experience, forming a typical "father's love deficiency syndrome", such as changeable mood, reticence, lack of communication with others and lack of enterprising spirit. Therefore, we should fully understand the importance of father's role in family education, give children a sense of security, enhance their ability to face the outside world, and enable children to face and deal with setbacks more actively.

In our country, psychologists have studied the parent-child relationship, children's socialization and personality in recent years, and have also drawn some very valuable conclusions. For example, the more time a father has contact with his children, the stronger the children's social communication ability, the stronger their adaptability to strange environments and the better their interpersonal relationship with others.

The father passed on a male behavior to the boy, which brought a sense of security and trust to the girl. In the child's mind, the father is an example and the object of imitation. In adulthood, fathers have a growing influence on their children. Father-son interaction can not only make children gain more social experience, but also bring care and warmth to children, help children develop an optimistic and positive attitude towards life, be willing to make friends and establish stable and good interpersonal relationships with others. At the same time, for girls, establishing close parent-child relationship with their father will help to avoid shyness in future communication with the opposite sex.

There is no unified model for successful fatherly love, and there is no fixed template for successful fatherly love roles. A successful father should be a child's teacher and friend, who can not only enlighten the child's wisdom, but also talk to each other and be intimate, helping the child solve some puzzles in life and psychology.
