HOHHOT, May 19 (Xinhua) -- After two years of research, archaeologists Friday confirmed astronomical engravings had been found on a 2,000-year-old rock carving in north China's Inner Mongolia Autonomous Region.
The five holes spanning a distance of 1,000 meters were found in moorstone rocks in Yinshan Mountains in the regional capital Hohhot, said Wu Jiacai, archaeologist with Inner Mongolia Normal University.
Yinshan Mountains are famous for a large cluster of ancient rock paintings, and the carvings were found when archaeologists surveyed the area in 2015.
The 2-to-7-cm-deep holes, with diameters between 6 and 10 cm, form a string similar to a pearl necklace.
