Late Shang at Anyang

The oldest extant direct records date from c. 1250 BC at Anyang, covering the reigns of the last nine Shang kings. The Shang had a fully developed system of writing, preserved on bronze inscriptions and a small number of other writings on pottery, jade and other stones, horn, etc., but most prolifically on oracle bones. The complexity and sophistication of this writing system indicates an earlier period of development, but direct evidence of such is still lacking. Other advances included the invention of many musical instruments and celestial observations of Mars and various comets by Shang astronomers.
