1. What other wing chun lineages besides your Yik Kam has only one long form siu lim tao?

2. What other wing chun lineage shares the kuen kuit of your Yik Kam lineage?

3. If hei gung was always a major part of wing chun as you claim, why did Yip Man not teach it? Are you claiming to know more about wing chun than Yip Man? Why did not Chan Wah Shun teach it? Why did not Leung a Jan teach it? Why did not Yuen Kay San teach it? Why does Sum Nung lineage have a hei gung set that was added to his wing chun, and why would he need to add hei gung if it was already a part of wing chun? Since none of these masters taught that hei gung was a part of wing chun, were they all wrong and you correct?
