I see there is a seminar from Dr. Baolin Wu this February, also available as a webinar for $499:

Does any bum have any direct experience working with Dr. Wu or the 9 Palaces System? There is a thread on this topic from 2014 but not many details and I figured much has happened since then.
I have the book but I never read it. I'm thinking some video instruction from the master himself about the system will be beneficial, i just have to decide whether I want to part with 500 bucks....
