@ gerard - nice website, but did you realise you have a photo of Gu Ruzhang (the famous Beishaolin iron palm master) labeled as Guo Yun Shen in your lineage section? I have seen this mistake elsewhere, and although I pointed it out, the picture remained there, so you may have seen it there. Perhaps someone got 'divine crushing fist' mixed up with iron palm.
Sorry for thread derailment.
