Complete Interpretation of Textbooks, a synchronous supplementary series produced by Wang Houxiong, please note that it is a "series", so there is more than one!
What is a "synchronous course" is a one-to-one correspondence with the textbook courses. The textbooks used in different places are different, so the textbook Complete Solution is divided into different "regional" versions besides "subjects" and "grades". You can see it from the big characters and pinyin abbreviations on the cover.
So, take junior high school mathematics as an example:
Grades are divided into grade seven (1), grade seven (2), grade eight (1), grade eight (2), grade nine (1), grade nine (2) and grade nine (all one book).
Each grade is divided into People's Education Edition, East China Normal University Edition, Beijing Normal University Edition, Suzhou Education Edition, Hunan Education Edition, Zhejiang Education Edition and Shanghai Education Edition. ...
Are you sure you need to ask for a "full set"? ?
Different books have different prices because of different printed pages. After a junior high school book is 20% off, it's about 20-30. You can do the math.
