Exhibition Advancing with the Times: The Technique of Rubbing, scheduled to open to the public on Friday at Shanghai Museum, will show visitors China’s time-honored rubbing techniques with 37 pieces (or sets) of precious cultural relics, including bronze and stone artifacts and rubbing works from different times. It is set to run until October 8. As a vital documentary medium in Chinese history, bronze and stone artifacts started to record important information before the Qin Dynasty (221BC–206BC). In order to preserve and spread the information on these artifacts, ancient Chinese developed rubbing, a simple yet productive technique for duplicating the information. (Photo: Chen Xia/GT)
