What’s happened to Lau Shui’s Grave in HK

Well it was once on diamond hill with Chow Gar Praying Mantis kung fu on it since 1942 with the bones gathered in 1952. Then later it was changed to just to be named lau Soei, no Chow Gar Mantis on the grave, no one know why to this day. And now its moved to a new grave some where else in Hong Kong
