I ve been trianing only 2 yrs
Ive been told a story of the old days when yip_man was a 16 year old and kung fu fighters would fight on the roof tops apparintly a grapler said "the fight starts on the ground"
so yip man throgh him off the building and said "now your on the ground"

if some one can take a few hits then hit them places where they cant take a few hits that may sound violent but some one hits you once ya fall over hit ya head concust then dead some times in a selfdefence situation you need to take it a levil abouve the attacker. the harder they attack the harder they get hert use their momentim to create your Lin sil de da(attack and defend at the same time) good luck
ps i train in New Zealand.
