I recommend you getting the 4 vcds of these sets, I learned these set many years ago and these vcds follow exactly, plus they came from the people who created the forms.
One thing to note, although it is said the Cai Longyun created these forms, Shaolin
has always had a loose set of self defense techniques they called 18 Lohan Hands that are the identical movements, just not isolated into postures and put into a standard form.
So, if Cai did that, he may have used these loose techniques from Shaolin.
But, legend has it that these movemtns came from the Wah Quan style originally and a Shaolin monk was defeated by them and thus they incorporated the movements into shaolin.
But, since Cai's family style is Wah Quan (Hua Quan), then it all comes full circle?
Maybe he did not use the Shaolin moves to create his form, but both he and Shaolin got it from the same original source?
Also, another intersting note:
If you are into the Eagle Claw style, the first move of this 18 Lohan form is an eagle claw move (which is also done in Yue Fei style and also in some Fanzi styles).
Also, the first 5 movements of this 18 Lohan form are the 5 elements in the original order, before Hebei Xing Yi people changed the order.
In 18 Lohan the first 5 moves are the equivalent of:
1 - Pi - splitting - metal
2 - Zuan - drilling - water
3 - Bang - crushing - wood
4 - Pao - pounding - fire
5 - Heng - crossing - earth
And if you continue from there the postures of the animals from XY are found in the rest of the form in a rudimentary way, such as Eagle, bear, moneky, crane, horse, dragon, hawk, swallow, sparrow hawk, and others.
Weird, what does it mean?
