Each Sifu is different. Some emphasis all tools originally found in the WC system. Some only utilize certain tools that work for them....
Just because some Wc doesnt have elbows or knees...
Doesnt mean Elbow strikes and knee strikes are not Wing Chun?
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"
