Tai Chi is an ancient Chinese martial art based on the Taoist concept of Ying-Yang, the eternal alliance of opposites. The practice of Tai Chi primarily involves performing a series of slow, circular movements that resemble a silent dance, but actually mimic fighting with an imaginary opponent. The careful and constant practice of these techniques, thanks to their softness, circularity, and the slowness with which they are executed, makes the body more agile and harmonious, improves posture, and has a beneficial effect on the nervous system and circulation. The ultimate goal of this art is to stimulate the free flow of vital energy, thus restoring harmony and balance between body, mind, and spirit.
