Ha Noi is the capital of Socialist Republic of Vietnam. Ha Noi lies in Red River Delta and is situated in a tropical area having a strong monsoon influence. The name of Ha Noi (Interior side of a river) has been derived from an ancient language which is literally known as a land area located in the inner side of Red River. It does not mean that the city is inside the river, but it is embraced by about 100 km of the Red River dykes. Ha Noi has nine inner precincts (Hoan Kiem, Ba Dinh, Hai Ba Trung, Dong Da, Cau Giay, Tay Ho, Thanh Xuan, Long Bien, Hoang Mai) and five suburban districts (Tu Liem, Thanh Tri, Gia Lam, Dong Anh and Soc Son). hongngoc
