The two sister styles. What exactly is the difference between the two?
Some people say they are the same, just interpreted differently by two Masters, one a beer keg of a man, the other tall and skinny.
Some people say they have only minor similarities, but are quite different in principle.
It is well documented that both grand masters were good friends and relations. Both learned from some of the same teachers. Both shared a Kwoon at one point sharing the teaching of the students.
My take on it:
Loong Ying uses more waist rotation than Pak Mei. There are some subtle differences in stepping and footwork too. LY stance seems to be a bit wider and the weight a bit more forward. They do that zig zag stepping too. Not sure about the breathing.
I’m no Loong Ying expert, but our Si Gung was taught Ying Jau Lin Que from the hand of Lam Yeu Gwai, when he and CLC shared the Kwoon together. I believe that our Guangzhou branch of Pak Mei has more dragon flavour than HK Pak Mei.
