Chi Sao constitutes the most important training method in the Wing Chun system. It is what Ip Man referred to as 'the Genius of Wing Chun'. Training in Chi Sao will help you develop contact reflexes, which are the key to victory in a live combat situation.
Chi Sao training develops close-quarters co-ordination and close-quarters focus, improving mobility, balance, timing and accuracy, while creating ample targets and openings to attack and counter.
