I bought many books on Chinese studies for my children. Finally, I think it is suitable for first-grade children to read the series (three-character classics), (disciple rules) and (200 lessons of ancient Chinese for primary school students). The first two books are required reading, but not comprehensive. They can be read as extra-curricular books, covering all the classic ancient texts and poems, with interesting illustrations. Illustrative forms can help children understand and strengthen their memory, which is most suitable for first-grade children.
