Hi Pak_Satrio and thx for the questions!
As I haven't studied Mo Pai from an official school, I could not and would not make such a claim. But the principle of Yin/Yang fusion from within the lower energy center, aswell as the ability to "see" subtle chi flow and project without touch, remain the same. The main difference is that Master Chang was able to have perfect control in regards of both application and intensity. I am nowhere near his level (should start meditating to do so) so the effect on my clients vary a lot. Some, you don't see much...others start to resemble the video fragments we all know from ring of fire. I'll go through my archive to see what I can dig up that is noticeable on video. I'll try to have this done this week, but can't promise 100% as I am the middle of relocating with the clinic (naturopathy pain clinic) to a new location.
