Four-year-old babies are suitable to learn character recognition first, as their language and cognitive abilities are not yet at a level where they can fully understand pinyin. Character recognition refers to learning to recognize Chinese characters, which is the foundation of Chinese language learning. Through recognizing characters, babies can gradually understand the basic elements of Chinese characters such as their structures, shapes and strokes, which will help them learn pinyin in the future. At the same time, recognizing characters can also stimulate babies' interest in Chinese characters and writing, laying a good foundation for future learning.

When children start to develop an interest in some simple Chinese characters, parents can assist their children to learn some simple Chinese characters, such as body parts, names of family members, etc. These are the Chinese characters that children often come into contact with in their lives. When children have a certain foundation of recognizing characters, then gradually guide them to learn pinyin, so that they can learn to spell Chinese characters, which can improve their reading and writing skills.
