There has usually been the cultural collision and fusion between civilizations in the process of nationalization.In the 1990 s,the resettlement policy of the hill tribes to the low land area made by the government of Muang Sing County in Luangnamtha province of Laos which aimed at the strengthening of government’ s management of the hill tribes and the attempting to discipline the ‘savage’by the ‘civilization’in plain area failed due to the refusal of hill tribes to go downhills.Whereafter,the government carried out the work on drug control in mountain area,at the same time,promoted the "shifting cultivation"industry and development of job market.This made the hill tribe Akha who lost their economic sources go downhill to find new solution.The Akha who migrated to the low land area kept seeking to improve economic life and in the meantime to carry out cultural adjustment actively in order to merge into the "civilization"course.In addition,they also strived to maximize rights and interests in the process of nationalization.
