History 
At the beginning of the Bronze Age, the Viet tribe groups had settled down in the North and in the north of Central Vietnam. There were about 15 groups of Lac Viet tribesmen living mainly in the northern highland and delta and a dozen Au Viet groups of tribesmen living in Viet Bac, the northern region of old Vietnam.

The Weather 
Being over 1,600km long, Vietnam experiences some distinct climatic variations.
Northern Vietnam - has two distinct seasons - hot and wet summers and cool and dry winters.
Central Vietnam - coastal areas are more temperate than the sticky south (although they do experience high rainfall), while the Central Highlands are pleasantly cooler.
Southern Vietnam - is fairly consistently hot and humid all year round.
Carry a lightweight jumper as it can be chillingly cold inside air-conditioned buildings during summer.
