Bình Trị Thiên
Bình Trị Thiên was a former administrative grouping of three provinces in Vietnam: Quảng Bình, Quảng Trị and Thừa Thiên. The grouping did not work well and was reversed in 1992. The geographical term had been used previously, for example in relation to culture, folk songs and is still used after, for example in relation to dialect and folk songs again.
