Heh, I'm just trying to ruffle some feathers and try to be critical about one of the biggest myths in the Karate lore.
So people generally go on saying that the roots of Karate are in White Crane Boxing of Fujian province, China. However, this is devilishly difficult to confirm and particularly dubious since the claim is that teacher of Kanryo Higaonna (master of Goju-ryu founder Chojun Miyagi), Ru Ru Ko, is Xie Zhongxiang. Xie Zhongxiang himself was not a practicioner or teacher of White Crane but Minghequan (or Crying/Calling Crane), which itself is a hybrid of Southern Luohan and Crane methods. Assuming we know nothing of Crying Crane (and that the connection to him is certain), we should be equally safe to assume that Karate traces itself to Luohan as well.
Now, how certain we are that Goju-ryu (at least) has Crying Crane at its core? Easiest thing is to look at the katas. If Higaonna has been a student of Xie Zhongxiang, he should have learned some Crying Crane routines. So which forms does the style teach nowadays? Apparently at least following: Babulian, Ershiba su, Zhongkuang, Roujian and Qijing. They might also have Sanchin, but I cannot verify it 100 %. Higaonna himself, however, most likely taught only four katas: Sanchin, Seisan, Sanseiru and Suparimpei. None of the forms match.
We could of course go on saying that these Crane forms have been added later on and were not among those taught by Xie Zhongxiang. To scrutinize this, we have to look at his other students and see what they have taught. Luckily we know one, Huang Xinxiang. He was later in his martial arts career a student of Taiji master Zheng Manqing (is usually written, like, Cheng Man Ch'ing or something?) and later created his own Huang-style taiji. This style of taiji is curious since it actually contains few crane forms. Which ones? Babulian and Ershiba su, renamed Sanfeng Kuaiquan (Three Peaks Quick Fist; after the peaks of Wudang mountains, I guess). Thus we can say that Xie Zhongxiang taught at least Babulian and Ershiba su, but Kanryo Higaonna never learned those core forms of the style. Why?
To me the simplest explanation is, already with this non-historical forms transmission only -analysis, that Xie Zhongxiang is NOT Ru Ru Ko and Crying Crane has nothing to do with karate.
What do you think?
