I learned 8 Chain punch but the precise details escape me.
Would someone be so kind as to write out the moves.

I ask this question because I believe that this basic exercise is another version of what TJPM calls "strike four doors".

According to my understanding this method as I learned it from TJPM's Mantis108 should be among the oldest and most important aspects of PM.
It is quite simple though, as any good theory should be.

Confirming the similarity will be one more step in connecting WL Mantis to Sun Yuan Chang's lineage as I believe with a small degree of evidence that that is where WL PM's mantis comes from.

Furthermore, if someone can get MC Chan's ear it would be nice to hear the Chinese name of this 8 chain punch. I think a language barrier has caused it to be translated not quite perfectly.
