This is one of the best, if not the only secular resources for learning the Hmong Language from the beginning, as well as learning the grammar of the language. You can download the book here. If you are more of a book person, you can take this file to a place like Office Depot and ask them to make it into a book for you and it will probably cost around $50.00 (ask first, of course). I (Travis) Highly recommend studying this book if you are wanting to progress in the Hmong language. WARNING: Contains some explicit anatomical images which may be in appropriate for young children.
Note – This audio appears to have been originally part of the section on page 219 of the book which, incidentally, is missing from my copy. If anyone finds they have a copy of this book which includes this section, please let me know and I will eventually upload it. Thank you!
