The Thu Bồn River (Vietnamese: Sông Thu Bồn) is a river in central Vietnam, located near Quang Nam Province. From its source near the border of Quang Nam and Quảng Ngãi provinces, it flows northwest through Bắc Trà My, Phú Ninh, Hiệp Đức and Quế Sơn districts; turning northeast, it forms the border between Đại Lộc district and Duy Xuyên district, before emptying into the South China Sea at Hội An.
The Thu Bồn valley was a centre of Champa culture from 700 until the Vietnamese conquest in 1471. Cua Dai Chiem was the Champa port on the estuary of the river at Hội An. Today boat trips up river to Mỹ Sơn are one of Hội An's tourist attractions.
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 conical hat 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.
