I have some questions about why we do the things in Siu Lim Tau that we do, mostly the "second part"
The motion where you have your arms crossed and that shoot out to the sides. I'm hard pressed to think this is some sort of attack if you have an opponent to the arms length and side of you....
Same question for the two hands shooting behind you. This does not seem very wing chun... What is the purpose?
Thanks friends
As long as you do Wing Chun you will be discovering new applications for these movements for years to come.
So no matter how weird the movement seems to you at the moment , have faith that there is a very sound logical reason behind it .
The movements in the form are a set of exercises , as well as having a multitude of applications for each particular movement.
You say
hands shooting out to the sides , in our lineage they are slashing out to the sides.
This has many applications , in its simplest form it is a strike to the side of you , using anywhere from your elbow to the edge of your hand depending on the range of the attacker , usually paired with a pivot to increase power.
But I can also use it to deflect an incoming straight punch from the side , redirecting the punch and simultaneously striking his throat , similarly I can use it to collapse a boxing type guard from the side and strike through with the edge of my hand , with out having to orientate myself to square on to Pak Sau and punch.
The movements where you are palm striking down are mostly palm striking exercises , to teach you proper use of the elbow and the wrist and increase shoulder flexibility , particularly with the double palm strike to the back.
But these also have applications as well , as has already been mentioned the double palm strike to the back is a strike to the groin or bladder area when a opponent has you in a bear hug and both your arms are trapped and the level of his grab is around your elbow joints or lower.
A lot of people get this one wrong because they start trying to use brute strength to try and muscle their forearms around to the back and they find the partner can resist ,
DONT.
As with everything in Wing Chun it begins from your elbows , use both your elbows to
expand outwards and towards the rear first . Exactly as you do after you have done your two palm strikes to the side in the form
Expanding your elbows first creates a little bit of space for you to get your arms around to the back and strike the groin , usually because the points of your elbows are pressing into his arms and causing him pain.
Sometimes just the fact that the points of your elbows are pressing into arms will be enough to get the release all by itself.
