The history of China's calligraphy can be traced back to the Neolithic Age 6000 years ago. In Yangshao cultural sites in Shaanxi, Henan and Shandong, we can see its earliest expression from various patterns and symbols carved on the surface of painted pottery. However, according to the analysis of existing data, the pattern symbols on these cultural relics did not have the elements of calligraphy before the Shang Dynasty. Only in Oracle Bone Inscriptions and Shang Dynasty, when the three elements of writing, calligraphy and composition were all available, could it be called calligraphy worthy of the name.
