The second major group in Thailand, the Njua Hmong vary considerably from other Hmong groups and indeed some ethnologists even consider them a separate ethnic group. Again sub-groups have widely varying dress and correspondingly different names in different regions. They may also be known as White, Green or Black Hmong, but in Thailand they are most commonly referred to as Blue. Clothing, particularly skirts, is very bright with multi-coloured hoops and patterns on a blue background. In other areas red may predominate and Hmong wearing dresses bearing vertical instead of horizontal designs may be termed Striped Hmong. The bright Hmong-style handicrafts you come across in markets is generally based on Blue Hmong designs.
Blue Hmong are generally found slightly more to the west than their White cousins. Traditional houses are wooden and bamboo constructions built directly on the ground with beaten earth floors, unlike the stilt houses of their Akha neighbours. While in past times they were animist, most groups have since converted to Buddhism or Christianity. As with all the Hmong clans, they are considered to have originated in Southern China.
