Making rubbings for tablet inscriptions is a craft with a history of over 1,000 years in China, invented as a way to copy documents even before the art of printing. Upgrading the traditional rubbing craft which can only be applied to flat surface, Li Renqing, born in 1963 in Xinyang of central China's Henan Province, has been working for a whole life on rubbings of high relief cultural relics, making the once impossible task a mature craft.
