Sister Xiang and Brother Chou are children's books. Reading this early education book can help children understand the world and promote the development of their brains.

Early childhood is a critical period for the development of life intelligence. Grasping early education can improve the learning effect. For example, some people think that early childhood education is the best age for children to learn oral English at 2-3 years old; Foreign language learning should not be over 4-5 years old at the latest, because at this time, children will not be confused with their own language; 5-5 and a half years old is the best age to master the concept of numbers; 6 years old is the best age to develop size and orientation perception. Bloom, a famous psychologist at the University of Chicago, published the book "Stability and Change of Human Characteristics" in 1964, and put forward the famous hypothesis that children's intelligence develops fastest before the age of 5.

Early education can promote brain development. Some parents worry that early education for their children will damage their brains. In fact, this kind of worry is unnecessary. Some researchers use animal brains and biochemical changes. Facts show that adequate environmental stimulation and learning opportunities in the early stage will not only damage the development of the brain, but also promote the development of the brain. Early education books are part of parenting. Early education is a complicated and diverse process, and early education books can provide reference for parents to better educate their children.
