The culture Bhutan is among the oldest, most carefully guarded and well preserved cultures in the world. Bhutan's culture is the only highlight of this small and less developed country. Bhutan has three main ethnic groups: the Sharchop in the east, which originated from the tribes of northern Burma and northeast India; the Ngalops in the west, who introduced Buddhism to Bhutan after migrating from Tibet; and the Lhotsampas in the south, originally belonging to Nepal. Bhutan has a population of around 700,000. Thimpu, the capital of Bhutan is one of the large towns in Bhutan. The major profession of the people of Bhutan is farming, who live in small rural villages. These villages are secluded and is accessible only by foot. But now, as the people are getting educated, they are migrating to towns in search of other occupations.
