The lineage claim is just a game Feng Shui practitioners love to play. Most schools claim Yang Jun Song 杨筠松 (better known as Yang Jiu Pin 杨救贫) to be the founding great grand master. Come to think about this: Where and from whom did Yang Jiu Pin learn Feng Shui?
It is interesting that no one suggested he got the knowledge from some aliens who were much more advanced than our civilization. It is the only sensible answer if the lineage game is to be convincingly played.
People who know me well understand that I learned Chinese Metaphysics from ancient books under the guidance of an old master. Our relationship is just like that between a doctorate student and his professor. The lineage game is not played in universities but there may be a school of thought honoured by people with like minds.
The lineage game has suffocated the development of Chinese Metaphysics. I am giving out the wake-up call to dreamers and if my voice is not loud enough, please join me.
