Uncommitted techniques in Wing Chun

Wing Chun 詠春 is a concept-based Chinese martial art and form of self-defense utilizing both striking and grappling while specializing in close-range combat.

Wing Chun techniques are uncommitted. This means that if the technique fails to connect, the practitioner's position or balance is less affected. If the attack fails, the practitioner is able to "flow" easily into a follow-up attack. All Wing Chun techniques permit this. Any punches or kicks can be strung together to form a "chain" of attacks. According to Wing Chun theory, these attacks, in contrast to one big attack, break down the opponent gradually causing internal damage. Chained vertical punches are a common Wing Chun identifier.

 Wing Chun teaches practitioners to advance quickly and strike at close range. While the Wing Chun forward kick can be considered a long range technique, many Wing Chun practitioners practice "entry techniques"—getting past an opponent's kicks and punches to bring him within range of Wing Chun's close range repertoire. This means that theoretically, if the correct techniques are applied, a shorter person with a shorter range can defeat a larger person by getting inside his range and attacking him close to his body.

Wing Chun is based on 3 principles, namely:

- Simultaneous Defense and Counter Attack by Interception
- Economy of Motion in every Techniques
- Centre Line
