The Hmong traditionally farmed in the mountainous areas of China, Vietnam, Laos, and Thailand. Most of the Hmong were subsistence farmers who grew only enough food to feed their families, because farming was difficult in the mountainous regions where most of them lived.
Whilst many Hmong are still left in Laos, Thailand, Vietnam, Myanmar, and China (which houses one of the biggest Hmong populations in the world, 5 million), since 1975 many Hmong have fled Laos in fear of persecution.he clan (xeem) remains a dominant organizing force in Hmong society. There are about eighteen Hmong clans that are known in Laos and Thailand. Clan membership is inherited upon birth or occasionally through adoption. All children are members of the fatherâs clan, through which they will trace their ancestors.
