Sorry for the confusion. Yes I have always known Tai Chi Chih as Tai Chi Ruler. I learned the basics in China ( in a small town just outside Xian) in 1996 from a Chinese gentleman whom I saw practising it but who had no English. I subsequently continued my studies with a teacher, here in the U.K. It is a superb exercise routine, both for martial and health purposes. It was supposedly founded by Chen Hsi-I in the 10th Century ( He is also credited with founding Liu Ho Ba Fa). But like so much of Chinese history facts are difficult to establish.
There is little published on the art, but I know Terry Dunn has done some work in this area via Dragon Door Publications (not sure of their current URL). If you get the chance, give it a try.
Very best wishes
