People visit a public exhibition of Chinese cultural relics returned by French private collectors, at Gansu Provincial Museum in Lanzhou, capital of Northwest China's Gansu province, July 20, 2015. Thirty-two gold ornaments stolen from ancient Chinese tombs and held by French private collectors Francois Pinault and Christian Deydier were formally handed over to Gansu Provincial Museum on Monday. The 32 gold items came from tombs in Dabuzishan in Lixian County, Gansu Province dating back to the Spring and Autumn period (770 BC-476 BC). The tombs were badly looted during the 1990s and a large number of relics, including the gold ornaments, were smuggled abroad. [Photo/Xinhua]
