Bac Ninh province (Vietnamese: T ỉ nh ắ B c Ninh/bac Ninh province) is a province of Vietnam, lies (to the) east of Hanoi, belongs to the red river delta. Divided from hebei province, it was called longbian in ancient China.
Beijiang province (Vietnamese: T ỉ ắ n h B/c Giang province beijiang) is a province of northeast Vietnam, located in the east of Hanoi.
In 1962, Vietnam merged bei-ninh and bei-giang provinces to form hebei province. The original hebei province of Vietnam came from this way. Good sense!
