For more than 50 years, rumors have been circulating about mysterious stone discs found in the central part of China in the Baiyan - kara - ula mountains. And for the same number of years the voices of skeptics have been heard denying the very existence of these strange objects. However, recent studies in the formerly forbidden zones of China by the German archaeologist Hartwin Hausdorff force us to return to this problem.
The first expedition to the extremely inaccessible region of Goo Baiyan - kara - ula (Qinghai province on the border of Tibet and China), led by the Chinese archaeologist Chi Pu Tei, took place in 1937-1938. The expedition found there a mass grave of strange, small creatures (1.5 meters tall) with disproportionately large heads. A total of 716 graves were found! And in each of them lay a stone disc 30 cm in diameter and about a centimeter thick. But the most interesting thing was that on each disk there was, like a gramophone record, a central hole, from which a double groove extended, reaching in a spiral to the very edge. And in it, completely unknown to scientists, letters like hieroglyphs could be seen. In addition, chemical analysis of the material showed a high content of cobalt and some other metal. The oscilloscope recorded an incomprehensible vibration at the disks. They were either charged from an electricity source or used as electrical conductors.
