Wudang Mountains
In China, tai chi is categorized under the "Wudang" grouping of Chinese martial arts—that is, arts applied with internal power. Although the term Wudang suggests these arts originated in the Wudang Mountains, it is used only to distinguish the skills, theories and applications of "neijia" (internal arts) from those of the Shaolin grouping, or "waijia" (hard or external) styles.
