Hello, I'm glad to answer your question. The "five fields" you asked are very vague. I guess what you might want to ask is the reason why there are "five games" in early education. Today's preschool education can be divided into five areas, namely health, language, society, science and art, which promote the development of children's emotions, attitudes, abilities, knowledge and skills from different angles. I hope I can help you and wish you a happy life.
