I have spent 47 years of my life studying Martial Arts and authored 13 books between 1982 and 1996. In 2007 I began training a Demonstration Team and subsequently developed and published five instructional DVDs. Two of them are my exclusive development of a system of self defense designed for lay persons wishing to learn an effective system of self defense using the Steel Telescoping Baton. The DVDs are entitled Tie Gun Lian Shi and Tie Gun Lian Shi Level II. The terms Tie Gun mean "Iron Stick" and Lian Shi is my style of Kung Fu. The thrid DVD is "Advanced Guge Gongji" which teaches structurally disabling an opponent in self defense; the fourth is "Fight for Your Life, Unarmed Against the Gun" which teaches techniques for safely taking a handgun away from an attacker, and the fifth is "Combat Boxing for Competition and Self Defense" which teaches basic and advanced boxing skills with a focus on systemic boxing and training methods. They're all on my website at www.longsystemcombativearts.com. In addition to selling these DVDs and a small number of training utensils on the website, I also sell to dealers and distributors at a 50% discount.
