That's cool to know, but its not a big deal really.

The wushu committee that created it just thought it was a good sequence of movements to make it easier for kids to learn long fist. Five year olds do it.

It's interesting that it is found in it's entirety in Cha Quan #5 and some other moves in other Cha Quan sets (there are three completely different Cha Quan systems, plus there is the modern wushu Cha Quan, which maybe that is what you are looking at?)
