“Lue” should not be a name for a group who portray themselves as a representative of cultural identity. The study of “Lue” in Thailand, Lao and China try to point out that being Lue is complicated including ethnical historical dimension, relationship dimension between the Lue and other groups in the nearby communities, power dimension which is classified and managed the culture by the government the Lue is a part of at the present and the linking dimension of the ethnical inter borcer of Lue in a country which relate to Lue or a group of people who speak Tai in other areas as well as the rehabilitated dimension which bring back some ethnical identity. This identity is lost, assimilated and destroyed by the government. This process is a negotiation between the minority and the government by cultural practices in community and inter state level.
