WOW.. This is really good stuff. I 've been very curious lately and have been reading books and stuff, i even bought china's history books to see if there is any correlation, but nothing like this is written. Even if these are speculations it's quite logical. Don't take any offense, i'm still trying to learn as much as i can.
Well, that's awesome that you're "curious" and "reading books and stuff". I'm not sure what books/stuff you have presently but here are some of my recommendation
s: 1) Hamilton-Merritt's "Tragic Mountains" - a must read for ANY/ALL Hmong, yeah it's Hmong SE Asia but will be a good foundation to expand on 2) J. Mottin's "History Of The Hmong" 3) Grahams' "Songs And Stories ... Ch'uan Miao" 4) Tapp, Culas, Lee "The Hmong/Miao Of Asia" 5) T. Vang "A History Of The Hmong", just finished this book, not great but good stuff in the first two chapters.
Well, those are starters if you truly are "curious". (I do hope you'll keep up your "curiosity". I AM and HAVE!!! Most of it is sad but makes me PROUD of my ancestors and who I am - being Hmong/Miao.)
As for the Ch'u Kingdom being Hmong, I have a couple of books that I have yet to read to clarify/solidify this hypothesis but from the sources/references I've come across so far it is NOT entirely Hmong. It was a kingdom of various ethnic minorities unified to defend/fight the invading Chinese (conquerors) which the Hmong/Miao just happened to be the majority in population, though not necessarily the main ruling body (king/queen). It is yet to be proven/determined by the books I have and have yet to read. (Until I know more, I am inclined to believe it was a shared political system without a central figure head/goverment - king or otherwise. More so it is most likely made up of numerous villages and townships with its own governors, mayors, clan leaders etc.)
What's most interesting with respect to the Ch'u Kingdom is the archeological discovery of "Lady Di". I'll let the "curious" research this on their own. One conclusive analysis by experts (Chinese) is that this aristocrate was definitely NOT Chinese.
