China's first 3D glass-bottom bridge over the Yellow River

Tourists pose for photos on the glass-bottom bridge over the Yellow River in the city of Zhongwei in the Ningxia Hui Autonomous Region on Saturday, June 29, 2019. The bridge, which opened to the public in 2017, has 138 glass panels, including 61 pieces of transparent glass and 77 pieces of 3D-image glass that mimics the spectacular Hukou waterfall in the part of the river running through Shanxi Province.
