Hello, children's shoes ... Although this book was written by Tsinghua University, it was actually written by a teacher in our school, and it is only used in our school. (If you don't believe me, you can read the preface of the book, which mentions Nanxin University ...) So there are no related counseling books and workbooks on the market. I don't know why you need exercise books. In fact, the height is the same, and the contents of each version of calligraphy are similar. There is little difference between our school and Tongji Fifth Edition. There are many examples, and the exercises are all original questions. If you are interested, you can look at Tongji Fifth Edition's advanced math books and advanced math tutoring. Don't worry, at first, everyone thought the high number was difficult to understand, but in fact, they understood it later. If you want the answers to the exercises, I can only tell you helplessly … no … those questions can only be done by myself. It seems that it is the first time for us to use that book, and there are many mistakes in it. Come with the teacher and read more books. There are many counseling books in the library, so it is quite easy to get high marks.
