Hello, there was an extracurricular reading of high school history a few years ago, with a yellow cover, probably 15 yuan. I don't know if there are any now. That book is quite good. I also recommend the full interpretation of the senior high school history textbook edited by Xue Jinxing (general comment, the thick one is now the revised version of 18, in fact, the revised version of 15 is the best), which integrates the knowledge points of the existing textbook, slightly extends and is very detailed and in-depth, which is conducive to the expansion of historical knowledge and the consolidation of basic knowledge. In addition, Stavri Anoos's General History of the World and Jerry Bentley's New World History are both good professional history books, but they are voluminous works, and you may not finish reading them. I hope my answer is helpful to you.
