People view a digital screen of the installation "China Through Time" at the 71st Frankfurt Book Fair in Frankfurt, Germany, Oct. 16, 2019. Based on the original illustrations done by Chinese artist Du Fei and put forward by the Encyclopedia of China Publishing House (ECPH), the installation "China Through Time" was brought to an overseas book fair for the first time and was an eye-catching project at the book fair's THE ARTS+ exhibition area. On a digital screen -- 22 meters long and three meters wide, an illustrated panorama of the Grand Canal of China -- a UNESCO world heritage site, and its changes through history, were put to animation, with 1,700 figures, 200 boats and a myriad of details to look at.
