Tips from the Masters

Kühn, Cousergue: also called keichū. Neck, neck vertebra. Cousergue positions it rather in the middle of the neck.

Momot: Calls this Yamen (夜面) and provides a different description for Keichu.

Light blow affects the muscles and provokes headache. If light blow is directed slightly upwards, it affects cerebellum, and the person loses consciousness. Middle blow directed slightly upwards (30 degrees) and to the side (left/right) provokes shock, loss of consciousness, because occipital nerves are affected and infringement caused to spinal cord. Strong blow is immediate death because the cervical vertebrae are broken, they, or their fragments cause spinal cord infringement, damage to the arteries.
