Hi DanC,
Sorry to take so long to reply. I've been traveling a lot between CT and MA since I got back from Hong Kong (and my family's ancestral village of Ping Shan) in mid-December. I'll be posting some Youtube videos of some martial form demonstrations that I had videotaped at the Tang Family Ancestral temple (Yang Tai Chi, Chen Tai Chi, and Liu He Ba Fa). Answer: Yes, I have a book on both Flying Phoenix and I have a book on the TTP-31 Basic Meditations, which is the only level that can be taught through video medium safely. I have been working off and on for years on the FP Qigong book, and hope to have it done sometime late this year. The TTP-31 Book is actually much easier to write because (A) the instructions are very straight forward and can be easily illustrated and (B) I've been doing Tao Tan Pai the longest of all the arts that I preserve--since 1974.
Thank you and all fellow FP practitioners for your patience.
Happy New Year of the Fire Horse!! --and may it speed me to complete these worthy book projects!
Sifu Terry
