Wu An is named after the school of our White Crane grandmaster, Cheng, Gin-Gsao. The original Wu An school was where our shifu, Dr. Yang Jwing-Ming began his training while growing up in Taiwan. With blessings from Grandmaster Cheng’s family and Dr. Yang, we named our school in their honor.

“武安” 是我先父親啟至請示神明武安尊王命名的.

“Wu An” was a name chosen by my father after he asked for guidance from the folk deity Wu An. Following this tradition, I hope that you will carry on in the martial spirit of Wu An and spread the practice throughout the world.

– Stuart Tseng (Grandmaster Cheng’s son)

Wu An (武安) translates to “martial peace.” We incorporated the character for peace (安) in our logo to emphasize its importance as one of the ultimate goals for our students – striving for inner and outer peace through martial arts training. Dr. Yang has always underscored the martial moralities in his teachings and we aim to pass these values to the next generation of students.

Martial Morality YMAA

Dr. Yang, Jwing-Ming

Dr. Yang is regarded as one of the most respected and influential teachers in the martial arts and qigong communities. He began his training while growing up in Taiwan, studying White Crane, Long Fist, and Taijiquan.

In 1982, Dr. Yang established Yang’s Martial Arts Association (YMAA). The organization now has over 40 schools in 15 countries and is overseen by a Board of Directors. Dr. Yang remains involved as the Technical Supervisor.

To further share his knowledge, Dr. Yang founded the YMAA Publication Center in 1984 and has authored numerous articles, books, and videos. With a Ph.D. in Mechanical Engineering, Dr. Yang is known for using his scientific background to explain martial arts and qigong theories. He has been a pioneer in introducing many Eastern theories and practices previously unknown to the West. Dr. Yang’s works have been translated into more than a dozen languages.

In 2005, Dr. Yang established the YMAA Retreat Center to run multi-year full-time training programs and summer seminars. As of 2022, Dr. Yang has relocated from the original site in Miranda, CA to McKinleyville, CA.
