Hi Royal Dragon - thanks for taking the time to respond. We've probably just got a bit of confusion creeping in there. Modern Yiquan, as founded by Wang Xang Zhai dates from the thirties and fourties, as I'm sure you know. However, according to Wang, Xing Yi originally had no forms, and "Yiquan" was already being used to describe Xing Yi before Wang, by his teacher. Hope that clears that up.
