I suppose I'll "chime" in first with what I know from my first-hand experiences and cultural consciousness,
. Fyi - there is actually a folklore regarding the "txiv coj xai" but I'll let someone else tell that story/folklore.
jetter,
You couldn't be more wrong about your opinion of "txiv coj xai" or the fact that they do not know the words and meanings behind each/all of the verses/words they say etc. Perhaps you or your kind are clueless, but I assure you a lot of the "txiv coj xai", if not all of them, know exactly what they are saying and the meaning of each word etc. I admit, even I do not know some/most of the words spoken but that is mainly because in the "song(s)", some of the words are not in colloquial context. For example, we normally say "txiv", but in the song they say "txi" etc. etc. etc.; therefore for those who are clueless, obviously they will think it is Greek. And trust me, Chinese friend or not, he or she would be clueless too. Why don't you go learn "txiv coj xai" or "Ntawv Hmoob" if you don't know it, then perhaps you will not be so clueless,
.
To answer the question within this thread:
Qhuab Kom? --- that's basically the "Teachings (morals and values) of Life", for example, not to steal, gamble, commit adultery, and love one another etc. etc., to have and lead a good, fair, and rightgeous life
Foom Kom? --- this is the "Blessings or bestowing of wealth, health, and fortune", this is mainly what everyone wants to hear and know, and if the "txiv coj xai" is worthwhile etc.
