I think Cambridge children's English is good. Cambridge English focuses on cultivating English thinking, expanding English background knowledge, mastering the basic structure of English, and emphasizing the all-round development of English listening, speaking, reading and writing. Its knowledge, grammar items and vocabulary of discussion topics all exceed the new English curriculum standards promulgated by the state, which is more suitable for primary and secondary school students to learn.

Cambridge English is a mini-encyclopedia of English with novel content, rich topics and lively form, which covers all the topics required by the Ministry of Education. It embodies the important ideas and directions of education reform and development such as "education is growth", "education is life" and "education is social experience", and is a series of excellent trainings.
