Query: One can always brag own horse

I recently bought this book, and I must say emediately DON'T BUY IT ! Book has about 130 pages, and about half of these book is braging (hope that I used right word). It is possible that Sifu Lai Hung is real master, but this book is only moneymaker! There is only 40-50 pages of practical techniques, and very basic ones too. I would never recomend this book to anyone. There is much better boks like Shaolin Long fist etc.
