A conference marking the 90th anniversary of the excavation at Yinxu is held in Anyang, central China's Henan Province, Oct. 13, 2018. The Yinxu site, or Yin Ruins, in today's Henan Province is famous for the discovery of oracle bones and script. Yin was the last capital of the Shang Dynasty (1600 BC - 1046 BC) and excavation of the ruins officially began as early as 1928. A large number of heritages have been found at the site, making it one of China's 100 greatest archaeology discoveries in the 20th century. (Xinhua/Li An)
