Hi-
It is worthy to note that in North Shaolin Kung Fu there are five major branches.
Those being Wa, Fa, Pao, Cha and Sillum.
There are many subsets and systems under these.
North Shaolin or Bak Sil Lum from Kyu Yu Cheong is one of the five major branches.
The North Shaolin available through the site you have posted may be a conglomaration of sets from other branches, or post 1928 sets.
Bak Sil Lum however was codified and systematized to its zenith by Kyu Yu Cheong as late as 1935 from his previous instruction.
Systems such as “preying mantis” are considered North Shaolin but they are entirely different from Kyu Yu Cheong’s system.
The same can be said for any Northern Shaolin system that is not derived from the major 5 branches.
The five major branches were determined by the chinese in the early part of the 20th century in an effort to catalog the known martial systems of all china.
There is further derivation found in styles such as Choy Li Fut where you have a mix of southern styles and Northern styles blended together into a whole system.
There are two main styles of Choy Li fut those being Heung Sing and Bak Sing.
But the style of “Bak Sil Lum” is always containing the sets as passed down by master Kyu Yu Cheong. The only differences are found in whether or not the teacher has been given extra weapons forms that are northern otherwise the ten core sets and the two preliminary sets are always in essence the same.
I have not been exposed to any of the sets that I saw at the web site you posted, but that doesn’t mean anything. (I didn’t thouroughly go through it either
)
At any given time, there are at least 400 different styles of Chinese martial arts being propogated on this planet.
Some Shaolin,some taoist, others being village systems, others being family styles and yet others being composites of a few different styles.
Some systems are complete and many are not entirely there any more for a variety of reasons.
peace
