And what's interesting about this writing on these oracle bones that are over 3,000 years old is that modern Chinese script has actually evolved from this over 3,000 year old writing. Also in that Shang Dynasty, we see major bronze artifacts. And once again, it's the first real historical evidence we see of a reasonably large geographic area being unified around the Yellow and the Yangtze River. Now in that video on the Shang Dynasty, we talk about how it eventually falls in 1046 BCE, and it falls to the Zhou Dynasty. And the Zhou Dynasty, they defeat the last Shang Emperor, Di Xin, at the Battle of Muyi in 1046. And based on their view of things or current historical accounts, Di Xin became a corrupt ruler, he was under the influence of his consort, and the Zhous say, hey, the reason why we were able to defeat them and overthrow them and establish a new dynasty is because of the mandate of heaven. The mandate of heaven is this idea that will be incorporated by the Zhou Dynasty and then becomes part of Chinese culture and tradition for thousands of years after that.
