Prehistoric traces discovered in Ha Giang

Traces of prehistoric people which belong to the Hoa Binh - Bac Son culture, dating back some 6,000-7,000 years, have been found at Khuoi Nang cave, Thuong Tan Commune, Bac Me District in the northern mountainous province of Ha Giang.
During an excavation early November, experts from the Vietnam Institute of Archaeology and Ha Giang provincial museum discovered two ancient tombs. Bones and teeth found there reveal that the tombs buried an adult and a child with a layer of pieces of stone under their bodies.
Hundreds of ancient objects, especially stone tools such as axe, hoe and knife, along with a special mineral which was used to decorate the body of the death, have also been discovered at the site.
According to Dr. Trinh Nang Chung, head of the excavation team, Khuoi Nang cave is home to many generations of prehistoric people. Further research of the site is underway.
