In reflection, I have observed improvement in the following areas:
- stability of the central axis
- isolation of non-moving and moving parts of the body
- ability to perform fajin-like actions in more places of the form (although I don't really know what fajin is, one definition that Master Chen Zhonghua gave is speeding up the actions)
- redirecting incoming energy to the ground
- understanding where incoming energy meets the reflective energy from the ground, and how that point can be used as fixed point
- transfer of energy to the middle finger tip from the ground
- range of motion in both kuas
