The following is my answer:
In the preschool stage, literacy and writing do not have to be put on the agenda. The task of preschool children is to establish basic understanding and expression skills of language, including listening, speaking, reading, writing, etc. Therefore, in the preschool stage, attention should be paid to cultivating children's language, cognitive, social, and emotional development.
Of course, if children are interested in literacy and writing, parents can guide and encourage them to learn appropriately, but they should not overemphasize it. After all, each child's development speed and interests and hobbies are different. It should be based on the child's interests and abilities, respect the child's personality and characteristics, and allow them to learn in a relaxed and pleasant atmosphere.
In short, in the preschool stage, it is more important to cultivate children’s language, cognitive, social, and emotional development, and literacy and writing are only part of it
