Biu Tze requires a high level of understanding of Siu Nim Tao and Chum Kiu in order to appreciate and understand the energies and techniques that is teaches. The form contains finger, palm and elbow techniques that can cause an immense amount of damage and are potentially lethal. For this reason Biu Tze is only taught to advanced students that have the correct mentality and overall approach to Wing Chun practice.

One of the key elements of the form is to recover from a mistake that might be made by a Wing Chun Practitioner. For this reason the form is often referred to as “medicine hand”, as it aids recovery when most needed.
