Does anyone have a reference to this supposed claim of Moy, Lin-Shin:
The 'Xiantian Wuji' Sect is the line her late teacher - Moy Lin Shin - claimed (falsely) to be lineage holder.
As far as Mr. Sun is concerned, I'm only aware of students, at least in the west, who learned liu he ba fa, xing-yi and ba gua and possibly tai chi sword and sabre forms from him. If anyone has any other footage or links to video clips of him, I would be very interested to see them.
TIA,
Doug
