Yuèshān-guan [月山館; "Moon Mountain School"] is the name of a private training activity in near Seattle led by Mark Raugas that is concerned with the development of skill at traditional approaches to internal martial arts.

The core of our practice is centered around the Northern Wú (吴) Tàijíquán, Yin Bāguàzhǎng, and Hebei Xíngyìquán maintained as part of Yin Cheng Gong Fa North America. I am a lineal student of Zhang Yun, who studied under the late Grandmaster Wang Peisheng. From time to time, I work with experienced martial artists interested in these arts.

Yuèshān-guan is read as Gassankan in Japanese. In addition to Chinese internal martial arts, I have practiced portions of several older kenjutsu (swordsmanship) traditions from Japan. More information on my training background, interests, activities, and philosophy can be found at the writing project Inner Dharma. I can be reached at the email address below.
