The governments of that country are responsible for their wellbeing and educating them to follow the rules of laws of the country that Iu Mien are living in.” After the loss of their nation, the 12 existing clans of Iu Mien people had to separate into small villages due to the mountainous area and foot hill land. Each village consisted of 15 to 20 families. The majority of people in each village were related. In some cases, they kept their clan together. Their farming life style was slash-and-burn to clear the grass and trees and to fertilize crops. Hunting and fishing were their primary career for men to provide foods for their families. They hunt many different kinds of wild animals ranging from birds, squirrels, monkeys, deer, wild buffalo, to elephants. Iu Mien women's primary role is to take care of household chores and feed animals. Iu Mien's written language is similar to Chinese character which is for religious and chant only songs. No written language for daily speaking. Every five to ten years, the mountain where the Iu Mien people lived and farmed would no longer be able to grow crops because the slash and burn process destroys proper elements soils needed to grow crops in the region. They had to move to a new place and location in the deep tropical forest to start a new life and a new village all over again. Iu Mien people were scattered all over the mountains in China. The mountains where they lived became deserts because of the slash and burn farming. They looked for new places such as other mountainous areas to build new villages. They had to search further south and eventually moved into Vietnam. No known record indicates what year the Iu Mien had entered Vietnam because of the constant fear of persecution by the Chinese emperor. The method of slash and burn used throughout mountainous regions in China led to a drought which caused the Iu Mien people to migrate to Vietnam. They saw Vietnam as an opportunity to build new villages and cultivate forest for farming. The Iu Mien population gradually migrated into Vietnam, in the province called “Moung Lai.” The lands had rich natural soil. The Iu Mien people were able to produce enough food to support their families. However, the local people persecuted the Iu Mien. When one of the local people died, they brought the dead body to an Iu Mien village and put in front of Iu Mien hut house door late at night. At dawn the next morning, the Iu Mien found a dead body in front of their door step.
