If there are any Leung Ting people, I have to ask. I've seen this on Youtube before but last night I met a guy and saw him perform it in person, and it blew my mind.

I'm talking about the gaang-sau section of SNT, where the hand lifts up to head height way out on the side, then does hyun-sau up in space. My mind can't conceive of what this might be doing or why.

Could someone explain it?
