For first-grade children, learning pinyin is easy for some children, but difficult for some children. Because Pinyin is a meaningless symbol, it only gives them the prescribed pronunciation for future literacy and reading services. Learning pinyin well is the key to establish students' confidence and interest in learning, which is of great help to their future study, especially their early reading. However, if children just can't learn pinyin, parents will have to pay more attention. Children may have learned pinyin at school, but they soon forgot it. Parents should be patient in adopting various methods, such as pinyin nursery rhymes, repeated memory and building block memory used in Kakafu's Happy Pinyin, to encourage children to learn and consolidate Pinyin in the process of application.
