Nice to know you are the Laopei!
Sorry, my english is not that good and for sure, I mix up sometimes, words and meanings. I´m very clear now about your words and your meanings.
Well, I heard about this 13 steps form first time from one of my students who went to Michigan at Han´s Seminar. When he came back he told me there was this new version of the form. Actually he didn´t learn it, just heard about it from someone there.
I could read an answer given by Master Yang Jun in this discussion forum to Michael Coulon the 09/19/2001 - you may find it here as well, searching in all the topics option.
There Michael also asks Master Yang Jun about this 13 steps form which some of his student could hear about in Michigan´s Seminar.
Your questions about it, are also mines.
