Taiji styles are named after the family that made them popular. The most common styles are: Yang, Chen, Wu, Sun, and Wudang. Each style has its own characteristic movements, and each style also has numerous different solo taiji routines. These solo taiji routines are the aspect of taiji that is most often seen in public, thus the common misconception that such a form is the whole of taiji practice. In reality taiji practice includes solo forms, partner drills, sensitivity exercises, self-defense applications, weapons training (i.e. sword and spear), secret qigong exercises, secret neigong (“inner skill”) teachings, and meditational development.
