- “Long Bridges” techniques in “Tiger Crane Double Form Set” (Fu How Seung Ying Kyun) come from “Buddhist Family Arhat Style/Set” (Fat Ga Lo Hon Kyun) – including the “Seven Stars Continuous Smashing Strikes” (Chat Sing Lin Waan Kau)
- Vast majority of “Five Elements” boxing techniques from the “Five Animals and Five Elements Set” (Ng Ying Ng Hang Kyun) are virtually the same as in today’s Hap Kyun
- We have a photo of Lam Sai Wing, performing “Wing-Flap Hand” (Pok Yik Sau) technique, which is not found in any today’s Hung Kyun set. The article mentions “Seven Stars Continuous Smashing Strikes” as one of the special methods of Wong Yan Lam’s disciple, Hap Kyun’s Wong Mun Wing (Wong Hon Wing) – read the article here.
- …and now, we have acquired a rare article series about Lam Sai Wing’s “Seven Stars Continuous Smashing Strikes [Set?]”, which btw. includes a drawing of the Pok Yik Sau – plus few other typical Hap Kyun techniques!

My Sifu told me that the “oldtimers” always squeezed the fists hard when training the sets for strength, slowly, each movement one by one. Think Jai Kiu, “Controlling Bridge” in “Taming the Tiger” or “Iron Thread”.
Hung Ga Grand Master Ho Lap Tin, one of the most senor disciples of Grand Master Dang Fong, dedicated a short paragraph to Grand Master Lam Sai Wing in his book “Hung Kyun Application Drills” (Hung Kyun Saan Sau) .
