Wing Chun is like snake/water adapts to your opponent in real fight--not a prearrange robot

Two ways of the 12 ways of attack demonstrated by Andrew Wang---a first year asistance instructor from Tom Wong's Wing Chun /Tsun school.
Some say we look like boxing, some say we look like Judo, some say we don't look like classical WC, the true is what you "see" reflects what you know, and very few can see how "sticky hand" work along our attacker's "trail" and finish him.
Real fight is a continuous float of movement. If you practice a "deadly set of techniques", it often end up "mis-matching" your opponent's attack.
This is the rarely seen Yuenkaysan-Sum Nung concept. Proper "Sticky hand" training can only learn from the right teacher, instead of learn by looking..."seeing is to be deceive, feeling is believing."
