Ancient currency-paved sidewalk seen in Zhengzhou

A 100-meter long section of a sidewalk is paved with ancient Chinese currencies, including the "Jiading Ingots," "Qianglong Ingots," knife money and Sankong-bu coins, in Zhengzhou City, Henan Province on November 12, 2017. These ancient currencies are engraved from thick stones and embedded to the sidewalk. Local residents say that the sidewalk was built several decades ago. [Photo: VCG]
