Wudang style martial arts developed in the mountainous region of Central Hubei Province, home to many Taoist palaces and temples dating as far back as the 7th century. Traditionally practiced by Taoist Priests, Wudang martial arts incorporates fundamental Taoist philosophy, including theories of yin-yang from the I-Ching, and the Five Elements: water, earth, fire, wood, and metal. The three most popular styles from Wudang Mountain—Taiji, Bagua, and Xingyi—are considered internal Kung Fu, focusing more on training the spirit, qi, and mind. Wudang Monasteries are increasingly featured in many Kung Fu movies, including as the setting in the last scene of Director Ang Lee’s Crouching Tiger, Hidden Dragon.
