Wudang's secret internal boxing is a shining pearl in Chinese martial arts and the essence of Wudang Kung Fu. It was founded by Zhang Sanfeng, a Taoist priest in the Northern Song Dynasty. It has a history of more than 600 years and was introduced to Yingshan County during the Yuan Dynasty. Wudang's secret internal boxing has been secretly taught in the Wang family of Yingshan County since the end of the Yuan Dynasty and the beginning of the Ming Dynasty. After 2002, Taoist You Xuande, the 14th generation descendant of Wudang Xuanwu School, became a naturalized citizen of Yingshan County and widely spread the boxing to the society in the region. Wudang's secret internal boxing is a precious boxing handed down from ancient my country; it uses stillness to control movement, softness to overcome hardness, slowness to defeat speed, and fewness to defeat the majority; it uses eight methods of yin and yang, rising and falling, opening and closing, bending fingers, positive and negative, advance and retreat, attack and defense, and alternating gains and losses; it integrates yin and yang and the five elements, combines it with Chinese medicine meridians, improves the functions of various systems and organs in the human body, and achieves the purpose of strengthening the body and the whole people's fitness. The unique techniques of "using martial arts to perform Taoism" and "using Taoism to demonstrate martial arts" are deeply influenced by Chinese classical aesthetics. They are like flowing water, continuous, moving like a snake, and quiet like a mountain. They soften the hard hair, wrap the silk and close it, and have a transcendent charm. At the same time, the Wudang School's secret internal boxing has attracted students from the United States, Russia, Italy, South Korea, France, Germany, Britain, Slovenia, Belgium and other countries to study in Yingshan Nanwudang with its unique charm, making a positive contribution to promoting international cultural exchanges.
