Bố Hải Khẩu

Bố Hải Khẩu lies in the low country of the Red River delta, where river branches meet the tidal coast. Silt deposited by rivers and sea built the land on which villages and fields developed. In the tenth century the local leader Trần Lãm chose Bố Hải Khẩu as his centre of power during the contest among regional lords that preceded the unification of Đại Cồ Việt.
