This book is a popular academic masterpiece that explores Chinese history through geography and interprets the logic o historical development. The author uses information on natural geographical factors such as climate change, natural disasters, and environmental changes recorded in ancient books, and references modern geographical scientific research results to observe and analyze the relationship between geographical environment and historical evolution, revealing the hidden dynamics between geography and history. The author proposes that the geographical environment not only interacts with historical processes, but also determines the direction of history and the development of major historical events, such as the rise and fall of dynasties, the division and unity of countries, the relocation of political and economic centers, and the formation and evolution of strategic channels and military fortresses. It is precisely because of the unique interaction between China’s history and geography that the country has become what it is today.
