And since our last discussion on this topic, almost a decade ago, do we have anything more definitive on either "Taoist Lee" or "Grandma"? Names? Locations? Others that trained with these two of such skill?
In relation to the kicking, it now appears that Kim Moo-Hong - at least according to the sources in this thread - may have had nothing to do with the kicking as it has been related for years...
And as far as the rank, the speed seems less relevant that the fact that the last three ranks, which are referred to by number and date as "RANK" were actually issued by students...
Just things for thought.
This is all I can gather and theorize from talking to GM and other senior Sinmoo masters.
It seems GM Ji and Kim worked together for less then a year as reported, however it's not clear who introduced what to the final kicking repertoire. Only Kim and Ji know for sure. They both were top Yawara students of Choi at that time and also were rivals in a sense. Ji says he learned the kick from Taoist Lee and from Choi (7 low kicks).
I believe due to lack of english GM Ji generically referred to the figures Taoist Lee and Grandma because both were Taoists. Lee was also a martial artists of unknown kind maybe native KMA. Its not clear if even GM Ji knows the exact style Taoist Lee practiced, Sam Rang Do maybe? GM Ji learned meditations and Chi Kung exercises from them and also a lot of self study. It also seems GM Ji was young when he encountered these Taoists and I'm not eve sure if etiquette allowed him to question them much.
There does seem some corroboration that GM Ji & Kim both received either their 7th from Choi through the KHA and at that time they were the highest ranked ever.
It doesn't really matter I think because GM JI went his own direction and did not follow GM Choi's system in the pure sense as we know.
Sorry no real new news.
