The Lisu migrated into Thailand from the area of the upper Salween River in Yunnan, they belong to the Lolo speaking linguistic group, together with the Lahu and the Akha, but unlike these tribes they do not have distinct sub groups. Physically they have the most beautiful women and the most handsome men and dancing at their New Year ceremony in their ceremonial costumes adorned with silver, they are a unique and moving spectacle. Marrying outside the tribe is fairly common because the man must pay a high bride price for a wife. They take life very seriously and the frustrations of dealing with bureaucracy, or in settling disputes, can easily lead to suicide or escape into the world of drugs.
