This is Part 5 of the books in Chinese History series. In this book, we will discover the Warring States (¿¿, 475 BC -221 BC). Welcome to the Chinese History series, a series dedicated to helping Mandarin Chinese learners improve Chinese reading skills. In this series, we will discover China's 5,000-year-old history. Each of the book will focus on one important ruling Chinese dynasty. The books contain numerous lessons in Mandarin Chinese. We start with a ruling dynasty specific preface (¿¿), a brief introduction to the dynasty or related themes, and continue to dig the important aspects of the ruling era, such as politics, economics, etc. in the form or chapters. Each book contains 5 to 10 chapters. For the readers' convenience, a comprehensive list of vocabulary has been provided at the beginning of each chapter. The pinyin for the Chinese text is provided after the text. Further, to enforce deeper learning, the English interpretation of the Chinese text has been purposely excluded. This would help the readers think deeply about the contents the way native Chinese think. In order to help the Chinese learner remember important characters, words, long words, idioms, etc., they have been purposely repeated across the book, and across the books in the series. Taken together, the books in Chinese History series will tremendously help readers improve their Chinese reading skills. I blog at: www.QuoraChinese.com
