Dear Yusshi
I have been a practitioner of Goju Ryu for over 42 years, and I have trained in Japan, Okinawa, and China, where I managed to traced some White Crane masters who practiced wha they call Tig-wa, more like the Koryu of Okinawa (classical) Well, bugger if I ever came across the Kata you mention my friend. Either your teacher learnt these at some very obscure and unknown Okinawan island very few people knows about, or I'm George Bush!
Nevertheless, one can only learn from this masters, and I for one would love to be able to see what this forms are all about,maybe then I could be of any help, me thinks.
