It's quite complete I bought three portable shorthand books for my son, namely, ancient poems and essays necessary for Chinese in senior high school, chronology of historical events in senior high school, and model essays with high scores in English in senior high school. "Ancient Poems Necessary for Chinese in Senior High School" contains all the ancient poems required by the syllabus, as well as detailed explanations. The chronology of high school historical events connects all the historical events that need to be remembered in chronological order. Knowledge points are not only comprehensive but also easy to remember. The examples in High School English High Score Model Writing Every Day are very good and can be recited directly. There is material accumulation behind the examples, which can improve children's composition scores unconsciously. This series is very suitable for reviewing before the third party exam in senior high school, and it is highly recommended!
