On 3 July 2007, an earthen pot of ancient coins weighing 20 kg was found buried at 500 cm underground in a paddy field and later sold for US$12.5 per kilo. This site is located in Tran Xa village, Ham Ninh commune, Quảng Ninh district. The coins were from the Tang dynasty period. Compared to other provinces in areas surrounding Hanoi and Hồ Chí Minh City and Đà Nẵng, Quảng Bình is the poorer province. Therefore, more and more young and educated here find their ways to the big cities and more industrialized provinces. In each commune ("xã", a rural subdivision of a district), there is a clinic and there is a hospital in every county, in Đồng Hới city, there are more. The Đồng Hới Hospital, which was donated by Cuba, was built in the 1980s.
