The foreigner class is specifically designed for people from other countries who come for a short-term or long-term stay. The classes are easier than the Chinese traditional class but they are more optimized to get an understanding of the Wudang martial arts and consider the fact that most foreigners are older than the 13y old students at the Chinese traditional class. 

Master Yuan Xiu Gang (Daoist Name: Shi Mao) is a disciple of the 15th generation of Wudang San Feng Pai and the direct Master of Michael Weichhard (Master Ziji). You can find more information about Master Yuan Xiu Gang on his website here!
