Yea I saw a couple of his other videos too but only the ones about speaking Hmong. Didn't check out his videos about speaking Vietnamese or Chinese.
I'd like to correct myself on a previous statement I made about him being wrong on making the h sound when he pronounces the word Hmong. In white Hmong you do make the h sound. In green Hmong the h is silent.
And phaj hauj (pronounced almost like pa-how)is the older original alphabet system of the Hmong language that was used before the English alphabet was incorporated.
"Nyob zoo hmoob thaib teb" is pronounced the same in green and white with the exception of the word "hmoob" in green the "h" is silent and in white they actually make the "h" sound. But like I said before, only some words are spelled and pronounced different, not all. For example the word "nam" means mom. It's pronounced like nah. Well mom in white Hmong is spelled "niam" and is pronounced kind of like nee-ah
As far as whether white came first or green did is beyond me. I don't know the history. But one thing for sure is that one is not an improvement or an evolution of the other. My speculation has just always been that way back then maybe different groups lived in different regions and developed different accents and minor differences in culture. Believe it or not, their are some prejudice between the two. But I see it kind of like the culture in southern California is different from the culture in new york among white people for example.
And about whether or not Hmong culture differs from here in the US verses the ones in other countries? Oh yea, definitely. They can differ from country to country actually. Like Hmong from Laos will differ from Hmong in china. I would not be able to even communicate with a Hmong in china. My brother went on vacation this year to china. He ran into a market place like an outdoor swap meet, and here was a Hmong booth selling clothing and they couldn't understand each other. They were able to say something along the lines of, you Hmong? Yes, Hmong america? Oh OK. And other than that they could not communicate
And about only Hmong in america responding to the YouTube video, well because the ones in Asia most likely don't have internet.
