Hei Long has one binding characteristic to all of his books: he takes advantage of the ignorant, giving low quality info behind interesting titles. His books are the epitome of the adage, "Never judge a book by its cover", although the word TITLE would better fit with Hei Long. He presents some of the most impractical teachings I have ever seen, perpetuating myths and further holding back the martial arts world in a sea of ignorant aspiring students.
