There is absolutely no difference between the martial arts (wushu) version of sword-postures and the "sword dance" steps we have seen in the upload of Nov 13 "Blade dance: from Classic to Modern without Zhang Ziyi (whew)". lot's more on the way: 八卦弧形钩镰剑 if you can read chinese and are desperate learn what arched sickle shaped swords look like ..pretty intense...you'll know more in a week. 47 moves/postures -- the russians are learning them... No blade no dance? We'll see... This dictionary of moves and postures is the best I've found on the subject: it represents the start, move,and stop positions found in "opera" tumbling and gymnastics, and forms one of the corner stones of the "classical" (gudian) system of "indigenous" Chinese dance reconstructed in the 1950s.
