First, the power generation,
By evidence,
In general, if we look at the power generation of say, Hung Gar, White Crane of fujian, and CLF. We can identify, Hung Gar is using the "lifting dead weight " type of power generation, White Crane of Fujian is famous for its snapping shock power generation, CLF is famous for its angular momentum swing.
As for WCK, WCK inherit White Crane of Fujian's Snap or "inch power from join force" and Emei 12 Zhuang's "snake slide worm moves" also the " squat lifting" type of power generation. These fusion make it suitable for close body action, one can see if one has this type of power or not by observing one' action while doing the Woodern dummy, WCK suppose to stay close, stick, and snap.... however, not every one or every lineage has this characteristic, IE if one using the General Southern TCMA's "lifting dead weight" type of power generation, one will not do the same thing but got to stay far from the Woodern dummy because the power generation is different. So does in application and real life action. different power generation means a totally different thing.
