On this Crash Course in World Mythology, Mike Rugnetta is teaching you about floods and deluges, specifically in China. In Chinese myth, flood stories pretty much all revolve around a guy named Yu the Great, or Yu the Engineer. In the distant past, he was tasked with stopping the flooding on the Yangtze and Yellow rivers, and he did it. After working on the job for 13 years. Yu also founded the legendary Xia Dynasty. Yu exists as a sort of model for future emperors. He works tirelessly on behalf of his people, and always does the right thing. He's a good emperor, and a model for rulers to emulate. He's also super cool, and can turn into a bear when he needs to dig really fast.
