Originating in what is now southern China and northern Vietnam, the Vietnamese people pushed southward over two millennium to occupy the entire eastern seacoast of the Indochinese Peninsula. Ethnic Vietnamese, or Viet (known officially as Kinh), live in the lowlands and speak the Vietnamese language. This group dominates much of the cultural and political landscape of Vietnam.
The conical Asian hat, sedge hat, rice hat, paddy hat, and sometimes known by the term coolie hat, although many people consider this term to be offensive, is a simple style of conicalhat originating in East, South Asia and Southeast Asia, particularly China, Cambodia, Indonesia, Japan, Korea, Philippines, India and Vietnam. It is kept on the head by a cloth (often silk) chin strap; an internal band of the same material keeps the hat itself from resting on the wearer's head. This style of hat is used primarily as protection from the sun and rain. When made of straw or matting, it can be dipped in water and worn as an impromptu evaporative-cooling device.
