Which situation is qaij kaus and which is the other kind?
That was already answered, but, to further clarify - ALL the muam phauj and/or txiv dab laug - they ALL "qaij kaus", meaning "tuaj nyuj" or "kills a cow" depending on who the deceased is.
As "luckyvang" already explained:
1) Muam Phauj "qaij kaus" if her brother is the one who passed away. Here, Txiv Dab Laug "tsis qaij kaus" but is on-hand as witness, mediator, and interrogator.
2) Txiv Dab Laug "qaij kaus" if his sister is the one who passed away. Here, Muam Phauj "tsis qaij kaus" but is on-hand as witness, mediator, and interrogator.
3) Cuas Nyab/Ntxhais and Xov Txiv Dab/Dab Laug "qaij kaus" too, but that's off topic -
(fyi - they father-in-law and the daughter-in-laws respectively)
Everyone is is basically "the other kind" - "mus nrog hlub, ua hauv qhua tab, tsis qaij kaus" - though a lot of folks "tuaj nyuj pab zaub" because everyone wants to out do each other nowadays (competition) --
