Here is my concern. Every MA system has
- power generation,
- body coordination,
- waist/hip rotation,
- weight shifting,
- ...
To me, those are the basic "building blocks" for that MA system and not "principles" for that MA system.
For example, the
- Taiji principles are ward off, pull back, press forward, push, ...
- Preying mantis principles are 8 hard and 12 soft (clinch, pluck, connect, hang, ... ).
- Long fist principles are dodge, spin, jump in, hop back, ...
- ...
Those all have nothing to do with power generation, body coordination, ...
