I was at the Tomb imyself. We have pictures and video footage dealing with the translation of the tomb itself. What I learn was anybody was capable of putting their name on a tomb or the own slab as well. To prove that point Yin Fu was not a main feature at the tomb. Liang Zhen Pu and Li Zi Ming lineage was the big crew that is all over that tribute area as TBT highlighted in the earlier post.
What does this say to me? That politics was an influence in that Tomb. It's about money over proper (or what I might deem as proper) lineage description.
Concerning the original question about Sifu Park's name on the "stele" for those that are interested in Pa Kua to make a journey there and see. I didn't go to the tomb to worry about any particular person name on tombs or not. I went to learn and be in the presence of a great martial artist energy and burial site. What I got out of it is a big history lesson that any Pa Kua practitioner should go and see for themselves. Books and pictures can be used to tell the author's story and not necessarily the true story. Moslems go to Mecca, Catholics go to the Vatican, and Pa Kua practitioners should go to Beijing to see the tomb.
