Library

This book is divided into three parts, which are categorized from each dynasty of China, the ancient Western Regions and ancient Central and North Asia. The Gregorian calendar is the main way to record time. For some important times, when the end of the summer calendar and the Gregorian calendar span two calendar years, the Gregorian calendar and the summer calendar are recorded at the same time. In addition, although myths and legends are not true history, they have been integrated into "culture" and most myths and legends are hazy and beautiful. Their historical role and historical value cannot be denied or obliterated because they are untrue, so this book also records them as they are.
