I recorded 5 Hmong folk stories from an old cassette that my grandpa recorded in Thailand in the 80's. All five of them are by Ntxhoo Xub Vaaj from Thailand. By far, I considered him to be the best Hmong story teller in Hmong Leeg. Below are the stories:
Ntshab hab Ntshaus
Heev Leej Pov Sis Txaam
Los Tuam, Los Lwm, hab Los Xaab
Nkauj Mim See
Paaj Dluag Kuab Ib
