"Hidden in a remote corner of Beijing's Ditan ("Temple of the Earth") Park is a small area with gongfu enthusiasts practicing their eight directions exercises. The men (and all visitors to this area seem to be men) balance precariously on a series of bricks and stones, carefully stepping from one to the next, the best proponents able to make many rounds."

Ba Gua Zhang is an internal martial arts style that involves dodging attacks and attacking while moving in complex circular patterns. A few practice Bagua Zhang while walking in a circle and stepping from post to post which are set in the ground in a circular pattern; or, walking on the ground between large posts sent in the ground in a circular or figure eight pattern.
Walking in circles for meditative focus is also part of the labyrinth traditions.
The symbolism of the eight trigrams also has relevance in this context.
