The second part of the Tai Ji system involves the well known practice of Tai Ji Quan. However, the full cultivation of Tai Ji is deeper than the series of slow coordinated movements. Tai Ji is the balancing interaction between yin and yang. The movements of Tai Ji Quan become the personified version of this; soft concealing hard, weak overpowering strong, ​balance between the two opposites. By practicing Tai Ji Quan one can open the channels of the body and relax tensions both physical and emotional. Tai Ji is also a great benefit to becoming internally aware. The main benefit, though, from the training of Tai Ji Quan is that it is a low impact style that can be progressed in at any age. Even though the training of Tai Ji does not require the expense of massive amounts of energy it is a lifelong experience that requires determination and a strong vigilance, consolidating the very idea of its own practice.

The final part of the Tai Ji System is the practice of Liangyi, from here written as Tai Yi. Contrary to Tai Ji Quan, balancing yin and yang, Tai Yi is defined as the separation of yin and yang. For this idea, Tai Yi uses slow and fast, soft and strong together to turn the internal energy into external strength through movements called Fajin, or explosive power. When yin and yang are separated through these movements, it is called the Two Extremes. Hence the namesake of the style Liangyi, meaning 'Two Extremes.' Tai Yi is known for its emphasis on body technique and coordination and the awareness and understanding ​of internal control.
