To understand the movement pathways of Taijiquan's force, practitioners often concentrate on training the hands and body. However, beginning from the feet is the essential path. To achieve this the focus of Taijiquan lies in cultivating the root. If the feet are unstable during practice, even if the upper body movements are correct, it will be difficult to manifest the characteristic whole-body integrated force of Taijiquan, because the power of Taijiquan originates from the root.
When practising, the mind should focus on both feet. The lower body must be stable, with the feet firmly rooted, the toes ‘gripping’ the ground, the Yongquan (Bubbling Well) acupoints hollow, and the centre of gravity steady. The feet must be solid, channeling the body's weight into the ground to generate a downward stepping force. During the form, one must constantly pay attention to the stability of the heels, clearly defining the feet's position, angle, shifts in the centre of gravity, and the axis of rotation to maintain dynamic balance. This reduces the burden on the knees and helps resolve knee pain issues. At the same time, pay attention to the transitions between the substantial and insubstantial in the feet—the substantial foot must be strong, while the insubstantial foot must be light and empty.
Power originates from the feet, passes through the waist as a pivot, and is transmitted to the point of force expression through the coordination of the body. The feet must step firmly into the ground to generate force, the legs serve as the main conduit of power, the waist governs the transformation of force, and finally, the force reaches the hands. This entire process must be executed seamlessly in a single flow.
Practising Taijiquan from the feet is a long-term endeavour. With prolonged training, the foundational stance work of the feet will become increasingly solid. In Tuishou it allows one to respond with ease, to disrupt an opponent's root while maintaining one's own centred stability.
