What is the most widely practiced Tai Chi form in the world? Depending on who you ask, the answer would be The 24-Pattern Form, The Peking Form, The Short Form, or The Simplified Form. So which is it? Any of the above, really. All of these names refer to the same Tai Chi form developed in 1956 by the Chinese Sports Committee. Sadly, one of the most elegant forms ever invented also has some of the most awkward names ever conceived.
