In translation, it means: Hmoob Siav. What I learned from my uncle, he went to China, traveling on in car to see a Hmong village in China, one of the elders waited for the Chinese to go away before they had their conversation.
On that same time, the Hmong elders say, "Koj yog Hmoob Mej Kuj, puas yog?"
My uncle said, "Aw, yog kawg."
The elder of that village said, "Peb Hmoob nyob tim Tshoob Kuj yog cov Hmoob Siav. Nej yog cov Hmoob Nyoos. Thaum ub mas, peb hmoob ib txwm tuas cov neeg suam. thaum kawg, peb yog cov swb. Suam ua rau peb kom peb xyaw rog tus lawm tus. Vim lis ntawd, peb yog cov Hmoob Siav. Cov Hmoob Nyoos yog cov tsis kam yuav cov suam kev cai. Nej yog cov tawm tsam cov suam; nej yog cov neeg xav kom muaj ywj pheej rau lawm tus yuav. Vim lis ntawd, nej thiaj lis tsis siav baum lis peb. Nej yog cov neeg nyoos nyoos, cov neeg tsis kam siav ib zaug rog peb haiv neeg."
Right when I heard this from my uncle, I realized that Hmoob Swv really means is that they were force to obey under the Han Chinese rule. The ones that went Caub Fab (Rebellion), they fled and didn't melt pot with China is because they didn't want a king who abuse their power and tell them what to do.
