Jin 勁 and Yi 意
Jin is elastic power, stored and released by the muscles, tendons and fascia like a drawn bow — and released loose, which the tradition calls Song. Yi is intention: not an energy itself, but the focus that controls how the energy is generated and released. In the Shaolin model Master Yap teaches, they are learned in order — strength, then Jin, then Yi, then Qi — and no level can be skipped.
