I think Hmong singers are becoming more like other ethnicities. Female singers like Ntxawm Lis, Cib Xyooj, Paj Suab Lauj and Maiv Xyooj (when she was married) continue their singing careers even after their marriage, but of course under the watchful eyes of their husbands.
However, for Hmong actresses I think most of the times they stop like Mab Sua Lis because acting is more demanding and it's more physical (maybe a little too inappropriate for married women. Hmong culture is a lot more conservative than Thai & Mekas culture).
Hmong actors on the other hand, if they're really into acting, like Kwm Lis,Tsab Money and Xaab Thoj will continue because it's accepted by the Hmong community that they're men and they know what's appropriate (Hmong culture somewhat assumes women are naive). Speaking of Xaab Thoj, I heard he got married.
