This book is another work of the author after Lu Feixue’s Revealing of the Internal School of Martial Arts, Revealing Secrets of Xingyi Boxing by Lu Feixue and Lu Feixue’s Revealing of Taichichuan and is also the last one of martial arts in the plan. The book is divided into three parts. The first is to decipher the method of the Internal School of Martial Arts; the second is to decipher the eight-trigram boxing; and the third is to decipher the imitative-styles (Xingyi) boxing left by Xue Dian. Because this is the last book on martial arts, the author has tried his best to make as many secrets of internal martial arts as public as possible. Most of the contents have only been passed down orally between masters and disciples in the past hundred years and cannot be read in written words, so it has very high academic value for practical reference and can be used as a boost for martial arts successors to improve their cultivation. After this book, the Lu Feixue Decrypting Martial Arts series will come to an end, and the author will interpret traditional cultural works of Confucianism, Buddhism, and Taoism.
