Where do you get this information from? Is it from others via internet forums, or have you actually spoken directly to Wang Liping and he claims to personally be able to make incredibly dense 500ft wide chi fields?
Has a Mo Pai student/teacher said anything about voltages corresponding to certain levels?
I'm just wondering if this stuff is 'commonly known' from some texts/teaching somewhere... or is everyone on this forum just making things up as they go along?
