Why would you try to carry argument from one place to another?
What did I say in that other thread? Part of his M.O..
Now, regarding HKM WC, it appears
jam-sau has also suffered the same fate in their lineage. It has completely disappeared.
The dichotomy between
taan elbow and
jam elbow is largely what the system makes use of for development of elbow behaviors in free fighting. As most of us know,
gaang-sau was added to SNT following one of WSL's fights where
jam-sau had failed and YM deciding that it should be introduced sooner than the dummy or
Biu-ji form. However, while WSL kept the important
jam-sau section, his contemporaries replaced it with the new
gaang-sau section.
As a result,
jam-sau seems to have disappeared entirely from their thinking, and this means that
taan-sau no longer has an opposing
jam-sau to work with, which has led to various application ideas for the
taan-sau shape which have nothing to do with the original function in training. Their focus has shifted away from the elbow, forward to the wrist, and the wrist is now used as they stick, feel, and redirect with one hand and strike with the other. This fundamentally changes the way the system works, removing simultaneous attack and defense functions in a single limb, fully castrating the "cut the way" strategy, and ultimately resulting in a far less efficient method.
This is a major difference between WSL's VT and that of his contemporaries, and it seems HKM lineage is no exception.
Two videos below show Lui Ming Fai demonstrating
daan-chi-sau, and we can see how his elbow pops out while his wrist drops to the level of the navel to redirect the incoming strike. In WSLVT, the
jam elbow comes in and forward to a punching position with hip connection and without dropping the wrist, then punches. It's broken up first to teach the elbow. Later, it turns into a single action.
Taan and
jam elbows are further developed in
pun-sau too, but this should be the first stage of their interaction... and yet it's missing.

In the last video, we can see how not only in their SNT form is the
jam-sau section missing, but throughout the form there is no
jam elbow at all. A result of this is then seen in their
seung-ma /
teui-ma drill where they are not using the
jam elbow because their focus is on their wrists. This means they aren't making the proper angle and their footwork is wrong, just moving back in a straight line.
With no
jam-sau, the entire system falls apart! Nothing fits together in coherent stages for development. Lonely
taan-sau, left to imagination, gets treated as a fighting technique. And the entire strategy is lost and replaced with sticky wrists.
This is one simple way to know if a system is broken in a YM lineage. Check if they are missing
jam-sau from the very beginning! If so, it pretty well guarantees they are going to have sticky wrists and fight with
taan-sau.
