First, preschool education is extremely important for the development of people's sociality and personality.

Preschool period is the initial stage and key period of individual socialization. Under the influence of acquired environment and education, infants and young children gradually form and develop their initial and most basic feelings and attitudes towards people, things and things in the process of interacting with people around them, laying the foundation for their behavior, character and personality.

Studies and facts show that before the age of 6, people's behavior habits, emotions, attitudes and personality rudiments are basically formed, which is an important period for children to develop good social behaviors and personality qualities such as politeness, friendliness, helping others, sharing, humility, cooperation, responsibility, generosity, liveliness and cheerfulness.

Moreover, the development of children in this period has a lasting influence, which affects and determines the development direction, nature and level of children's sociality and personality in the future; At the same time, children's good social and personality qualities formed in preschool period will help children adapt to the environment actively and social life smoothly, thus contributing to their healthy growth and success.

Second, preschool education cultivates children's self-awareness.

Self-awareness is the subject's understanding of himself and his relationship with the surrounding things, especially the relationship between man and me. The strength of self-awareness directly affects the development of children. The development of self-consciousness includes the development of physical and sensory consciousness, as well as the development of emotion. Children can look in the mirror very early and start to distinguish themselves from others, but many 3-year-old children are still superficial about the relationship between various parts of their bodies.

Knowing your external image is worthy of attention. Studies show that beautiful children are considered more confident and independent than unattractive children, while the latter are considered to have more non-social behaviors. Even 3-year-old children are more inclined to choose beautiful children when choosing pictures.

Beautiful children are more attractive and easy to establish good relationships with others; Children who are not beautiful are often overlooked. These in turn affect the development of children's self-awareness.

Age awareness is also more interesting for young children. It is difficult for young children to understand that the body will change with age. Even those children who already have a little brother (little sister) and know that the baby will grow up to be as big as themselves, it is still difficult to understand that mothers and teachers were once children.

Children's understanding of the concepts of life, growth and death is gradually emerging. They try to deal with such complicated problems in simple ways, for example, linking rest with death, thus becoming afraid of sleeping.

With regard to gender awareness, many 4-to 5-year-old children still can't fully know the constancy of gender. Children aged 2-3 tend to attribute positive aspects (such as good looks) to girls and negative aspects (such as selfishness and aggressiveness) to boys. Once children determine their own gender, they will soon learn the behaviors and gender roles expected by adults.
