From another direction, Chinese historical sources and mural paintings in the Tarim Basin city of Dunhuang accurately describe the travels of the explorer and ambassador Zhang Qian to Central Asia as far as Bactria around 130 BC, and the same murals describe the Emperor Han Wudi (156–87 BC) worshipping Buddhist statues, explaining them as ""golden men brought in 120 BC by a great Han general in his campaigns against the nomads."" Although there is no other mention of Han Wudi worshipping the Buddha in Chinese historical literature, the murals would suggest that statues of the Buddha were already in existence during the 2nd century BC, connecting them directly to the time of the Indo-Greeks.
