The Lisu originated in Eastern Tibet, with the first settlers arriving in Thailand at the beginning of this century. They are found in the northwest of Thailand particularly between Chiang Mai and Mae Hong Son provinces. Extroverted, ebullient and friendly, the typical Lisu has a wonderful joie de vivre, and is a warm and friendly host. They are often very enterprising, adaptable, and self confident. Although increasingly integrating into the dominant Thai society, many continue to retain their customs and costumes, language and beliefs. At New Year festival, in mid-January, dazzling displays of wealth are worn, including waistcoats and belts of intricately fashioned silver and hats with multi-colored pom-poms and streamers. Men wear green, pink or yellow baggy pant and a blue jacket opening vertically. The Lisu live at moderate to high altitudes when possible. Their houses are built on the ground, with dirt floors and bamboo walls around a central ridge. They live as extended families, the number of bedrooms after puberty. Every home has an altar at the back of the communal living area with a shelf holding vessels and incense sticks honoring their ancestors.
