Blue Sky and White Clouds Martial Arts

This book tells a little-known secret history of martial arts in the Song Dynasty... The author spent N years traveling all over China, reading and sorting out N ancient historical books, and finally deciphered the secrets of the martial arts in the Northern and Southern Song Dynasty. In this book, the author profoundly reveals the kindness, love, hatred, secret battles, and passionate life between the characters in the rivers and lakes during the "Water Margin" and "The Legend of the Condor Heroes" period. This book does not have the chivalrous tenderness of the martial arts of the Song Dynasty written by Jin Yong, nor the heroic spirit of the characters in the legend of the Song Dynasty uprising "Water Margin" written by Comrade Shi Naian. What is left in this book is just an absolutely funny classic of vomiting blood...
