"Washboard road" tests vehicle suspensions in east China

As part of the three-day Labor Day holiday, many tourists in east China's Shandong Province travel to the Tai'erzhuang Ancient Town, located in the city of Zaozhuang. To access the site, tourists have to pass over a 100-meter-long stretch of road with more than 50 speed bumps along it. The stretch has been given the nickname the "washboard road."
