The tiangan (what someone is calling the “24”) are different than either of the jibengong (basic training) sets. There is as well the jibenshoufa (or basic hand techniques) of which there are ten. In the Yizhong system these “static” postures are generaly taught later in the game. Gaoshi bagua is a very complex and complete method. The Xiantian (pre-heaven) changes teach Bagua shenfa (body-method). The Houtian (post-heaven) teaches usage.
Interestingly the tiangan is done by the Zhang Zhunfeng and Wu Mingxia branches but not by those in Tianjin.
Buddy
when walking the circle the hands are back to back not touching about the heigth of the navel, the “inside” hand goes upward and the “outside” hand goes down and to the outside, repeat on the turn. This uses the backside of the palms…it also makes a great strech. I believe this is one and two of four; front, back, right, and left.
I honestly know little about tai chi.
All I know is these palms work great for manuvering through people.
