Chi Sim's TYD is derrived from Animal Kung Fu. Just look at their body mechanics, and you'll see leaning postures, bending over, and jumping around. Nothing against them, but this all goes against the WC principles of economy of motion and self-centerline.
HFY TYD is about power generation, body alignment, targeting, leverage, and gravity control WITHIN the WCK core principles and concepts. HFY and Chi Sim TYD may overlap in some ways on a philosophical level, but in actual physical expression.. They are very different.
In regards to Kiu Sau.. again, their 18-point Kiu Sau such as "cat washes face" uses classical Animal Kung Fu physical expression. Bending and dropping down, extending limbs, 3-gate side/body etc... Which are complete no no's in HFY as they exemplify what we call long arm/short arm. Instead, our HFY Sei Buhn Dim Kiu Sau again reflects WCK core concepts and principles, and is an integral to our Chi Sau. Our Kiu Sau technology, has it's own facings, body karma, and timeframe usages that are quite different than Tan Bong Fook Chi Sau.
