is similar to Chinese characters which is for religious and chant only songs. There was no written language for daily speaking. When their soil was exhausted, they moved to a new place in the 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 sought new places in mountainous areas. They searched further south and eventually moved into Vietnam. The Karen The K’nyaw,() known to many as Karen, and to others as Kariang or Yang, are one of the largest hill tribes in Southeast Asia. The total number of Karen people is unknown as they are spread throughout Burma, Laos, and Thailand, and no reliable census has been conducted in Burma since the 1930s. Population estimates range from 7.5 million to 14 million people. (The more conservative estimate makes their population equivalent to that of Switzerland). The approximately 320,000 Karen in Thailand comprise half of the country's total hill tribe population. While the Karen still practice slash-and-burn agriculture as other hill tribes do, they differ in that they live in permanent villages at lower elevations and have been aggressive in developing environmentally sustainable terraced rice fields. These factors have allowed the Karen to better integrate themselves into Thai society.
