I personally love blind fold chi sau...it develops alot of key elements that transition to your fighting...
Chi Sau is akin to lifting weights, shadow boxing and or running.
You dont actually life weights, shadow box or run ten miles in a fight. But you do take the skills gain into a fight with you.
Chi Sau builds skills that you take with you into a fight...Same as hitting a punching bag!
The Flow is relentless like a raging ocean with crashing waves devasting anything in its path.
"Kick Like Thunder, Strike Like Lighting, Fist Hard as Stones."
"Wing Chun flows around overwhelming force and finds openings with its constant flow of forward energy."
"Always Attack, Be Aggressive always Attack first, Be Relentless. Continue with out ceasing. Flow Like Water, Move like the wind, Attack Like Fire. Consume and overwhelm your Adversary until he is No More"
