Vietnam (i/ˌviːətˈnɑːm/, /viˌɛt-/, /-ˈnæm/, /ˌvjɛt-/; Vietnamese pronunciation: [viət˨ naːm˧] ( listen)) officially the Socialist Republic of Vietnam (Cộng hòa Xã hội chủ nghĩa Việt Nam ( listen)), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.3 million inhabitants as of 2012, it is the world's 13th-most-populous country, and the eighth-most-populous Asian country. The name Vietnam translates as "South Viet", and was officially adopted in 1945. The country is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, and the South China Sea to the east. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976.
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.
