Features: Japanese ninjas and ninjutsu often appear in movies and TV shows. Their strange and unusual attire, elusive and secretive movements, and unique and highly skilled techniques have attracted countless martial arts practitioners. As the originator of Japanese martial arts, the profound and extensive Chinese martial arts—has it similar superhuman skills? The author can confidently say: Yes! However, due to the secret transmission, it remains unknown to the general public. The representative of Chinese ninjutsu is the Hei Hu Men (Black Tiger Gate). Because of its strange name, few successors, emphasis on medicinal skills, focus on night operations, abundance of hidden weapons, and deadly techniques, it has long been known as the "Black Gate" in the martial arts world and has been discriminated against by prestigious and orthodox schools. However, its unique techniques in combat and training hold great value for reference and are an invaluable treasure of traditional martial arts. If we can preserve the essence and discard the outdated, seek the right and discard the wrong, it will undoubtedly have significant practical meaning for the development of Chinese practical martial arts. Therefore, the author has selected the parts that can be shared and compiled this book to provide references, inspiration, and opportunities for creativity among martial arts practitioners.
