This work examined the creation of the Hmong identity at Doi Pui from the general perspective of traders of opium in the tourism perspective. The work gave a general overview of the opium trade history in China. Westerners used opium to intoxicate the Chinese in order to occupy China until the opium war during the colonization period. After having expelled Westerners, the government encouraged highland ethnic groups to cultivate opium. After conflict with the Chinese, the Hmong migrated to Thailand, Laos and Myanmar. The Hmong at Doi Pui came with opium. After opium was categorized as an illegal narcotic drug, the ethnic group turned the crisis into an opportunity by earning more income from tourism. The group has also adapted to globalization by contacting with the Hmong around the world to create its historical memories through printed materials, videos and weaving designs. The group takes pride in its ethnicity through cultural activities and “Hmong script” invented by Western missionaries and the Hmong in Luang Phrabang, Laos. The cultural activities and script have been disseminated to Hmong communities around the world including the one at Doi Pui.
