Chum kiu The second form, chum kiu , focuses on coordinated movement of body mass and entry techniques to "bridge the gap" between practitioner and opponent, and move in to disrupt their structure and balance. Close-range attacks using the elbows and knees are also developed here. It also teaches methods of recovering position and centerline when in a compromised position where Siu Nim Tau structure has been lost. For some branches, bodyweight in striking is a central theme, either from pivoting (rotational) or stepping (translational). Likewise, for some branches, this form provides the engine to the car. For branches that use the "sinking bridge" interpretation, the form has more emphasis on "uprooting", adding multi-dimensional movement and spiraling to the already developed engine.
