Octupole plus crack hanging, ghosts and gods are also afraid, crack hanging plus octupole, immortals are also difficult to enemy. It's a saying, the source of which is not clear, but there is a saying in Li's "Split Hanging Formula": "If ghosts and gods are afraid, octupole will be split hanging."

There is a saying that Tai Chi can level the world, and there are eight poles in martial arts, so there must be Gankun. There is another saying that is said by Gan Long, but it can no longer be tested, and there is no definite evidence to prove that Taiji Octupole here refers to Octupole and Taiji in martial arts.
