Can I trust the information in the Northern Shao-Lin Long Fist Book?
You can absolutely trust the information in the Northern Shao-Lin Long Fist book. Master Yang is one of the foremost authorities in the world on Shao-Lin Long Fist and Chinese martial arts in general. Jeff was his first ‘formal’ student. It is my understanding that as such, Master Yang imparted everything he knew to Jeff. But, that is another story unto itself which I am not qualified to discuss. However, having been a student and friend of Jeff for over 25 years, I feel confident in saying that there are only a handful of people in the United States with his knowledge, understanding and level of skill.
