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. And then they would interpret the cracks to see what was the answer to their actual questions. And you can actually see how this oracle bone script is related to modern Chinese script. So this is Shang written in oracle bone script, and you can see how it evolved over time to the modern day Chinese script.
