I was able to search for my old post awhile back:
Chi You/Txiv Yawg is nothing but a legend at this point. Chinese documents, more mythical than actual historical accounts, describe Chi You as having a part animal head and body and possessing multiple limbs. The great battle describes using breath of fog and bringing in spirits to aid in the fight. This sounds more like a fight in Final Fantasy VII video game, not a real war. This is a legend, like Zeus. Nothing more, nothing less.
Anyone who thinks he is the Hmong king and can wield a 100lbs sword into battle, based on legends and myth, is out of touch at a level beyond belief. There is not enough sufficient information to suggest Chi You was a real man in existence at some point in history or that Hmong can trace our lineage back to Chi You. Not saying that he was never a real person in existence at one time, but he sure didn't have an animal head and six arms or could breathe fog to obscure vision.
Another hundred years from now. Vangpao will be seen as a mythical creature that protected the hmong people from the vietnamese. I have even heard people making claim that vangpao
was a god among us.
Regardless of what folk hero image Vang Pao has hundreds of years from now, there will be written history as to who Gen. Vang Pao is, the "Secret War", as well as his life and death. However, you can't say the same for Chi You. Like I mentioned above, the only written documents concerning Chiyou is always something ridiculous like that he fought with a 100lbs sword as well as other silly stuff I posted such as being able to blow fog from his mouth to change the battlefield conditions.
If that's the kind of shit you take as truth, then that's your problem. I prefer to go with reality and (written) history. Legends and folktale are not history. But legends and folktale are a part of culture, literature, and life. Let's not discredit legends by comparing them with real written history because then, legends looks like horse shit next to written history.
