The forte of the Crane Style is in it's concussive strikes.
As Wing Chun is a derivative of the White Crane Style, we then must look at its concussive striking, but not simply in it's outward fisted applications. We must look at every tool and action within the style to derive it's full arsenal. Kyusho helps us discern what could be used as tools focusing on the bodies weaker anatomical targets.
One such tool is the ancient Shaolin Hand position named the "Blood Pool Hand", or also known as a "Hook Hand" or "Fook Sao" or "Tame Force Hand" in the Wing Chun Style. This technique is typically used as a deflection or as a controlling action of the opponents arms or on the neck. But the hand posture can also be used as an offensive tool, especially developed for the Kyusho Targets.
