The Luk Dim Boon Kwan - LDBK - Six and a Half Point Longpole Technique, is actually ‘foreign’ to Wing Tsun and was, according to legend, brought into the system by Leung Yee Tai who had learnt it from the monk Chi Shin in an exchange for the weaponless Wing Tsun.
Although stance and footwork is quite different from normative Wing Tsun, some effort has been made to bring it into harmony with the rest of the Wing Tsun System.
The LDBK form is quite short and consists of two sections (plus a basic exercise section) describing Stabs and different deflection techniques as well as methods to break contact with an opponents weapon in order to attack.
The LDBK System consists of the form, Chi Kwan (‘Pole clinging’) and actual fighting practice.
As with the BCD form, regular practice develops power and explosiveness but puts great stress on the joints and should be approached with some caution.
