Now what the Shang Dynasty is also well known for is their writing. It's the first evidence of a fairly advanced writing form, and it's related to modern Chinese. And a lot of that writing, the significant artifacts from that time, are on what are called oracle bones. That's an oracle bone right over here. This is actually the scapula, the shoulder blade of an ax. And what they would do is they would write questions in this oracle bone script on top of that scapula of an ax. And then they would heat it up in a flame or some type of source of heat until it cracks.
