Hello dear friends. I was searching about the forms of tang soo do, their history etc. Was sanchin kata (from Goju Ryu or another version) ever practiced in tang soo do? An article I found on internet refers that sanchin was listed by H. Kee at his second book as Tsan Tjin. I cannot find Kee 's books and by the way, the first volume is very expensive. Also I do not read Korean, so English books and googling are my only source of information.
