Greetings, I'm currently studying a Tai-Chi/Ba Gua Zhang combination style. I have been looking for information on it's roots, particularly the Ba-Gua Zhang, but have been unable to come up with anything so far. My teacher studied in mainland China under Jiang Yung Chiu for Ba Gua Zhang and under Ma Yat Ching for Tai Chi Chuan (I believe he is a Wu stylist) I began with three linear forms and am now focusing on the circle walking based palms. The style embraces the principles and flavor of Ba-Gua Zhang, and I don't question it's authenticity, however it seems quite different in the way the palms are executed from what I've noticed in western publications (Emei Baguazhang, Robert Smith, Kumar Frantzis, Liu Xing-Han and Lu Shui-T'ien) If anyone has information on the lineage of Jiang Yung Chiu or Ma Yat Ching I would greatly appreciate it. I realize I could ask my teacher, but I would rather use the few precious moments we have together working on my art, rather than asking idle questions.
Thanks

If you haven't found it already, there is good information on your style at Jereks site,
