These historical and cultural relics of the old city used to be scattered in backstreets and alleys, but now they have been connected with trails, looking like an old style painting. (Photographed by Zhao Zidong for Xinhuanet)

Chongqing has been dubbed as a "3D magical stereoscopic city." This is also the case in its trails. In the photo, in addition to Shangcheng No. 3 Trail (R2), another two trails were built on the hillside. (Photographed by Zhao Zidong for Xinhuanet)

Built on the hillside, the plank road also provides viewing platforms every tens of meters for citizens to rest and enjoy the views. (Photographed by Zhao Zidong for Xinhuanet) (Translated by Tang Zhiqiang, Fathom Language Limited)
