Graffiti left by unruly tourists on the Wuhan Yangtze River Bridge in Wuhan City, capital of Central China's Hubei Province. The bridge, an important project after the funding of the People's Republic of China in 1949, was included as a key cultural relics site under the state protection in 2013. Many tourists like to scribble a message on the bridge despite cleanup efforts. (Photo/CFP)
