MR.MA: The are several methods. The most basic of them is walking in a circle. It is divided into three so-called "basins" (San Pan): Lower Basin, Medium Basin and Upper Basin. Yin-Yang concept is very important as well - that's why we often call Bagua "Yin-Yang Bagua". Walking counter-clockwise is Yang, while clockwise - Yin. There are many requirements for walking practice: Hollow the Chest and Pulling Up the Back (Kong Xiong Ba Bei), Collapse the Waist (Xia Ta Yao), Twist Hips and Keep Knees Together (Niu Kua He Xi), Grasp the Ground Firmly with Toes (Zhua Di Lao); Drop the Shoulders and Sink the Elbows (Chui Jian Chen Zhou), Smooth Buttocks and Lift the Grain Path (anus) (Liu Tun Ti Gang), Three Pressing (Head Presses, Tongue Presses and Hands Press creating One Energy) and Three Round Principles (San Ding - Tou Ding She Ding Shou Ding Hunyuan Yi Qi - San Yuan). Only if all these requirements are strictly observed Internal Qi (Nei Qi) will appear and Neigong (Internal Skill) will develop. Once Neigong develops, it's like electricity in hands.
