It's called the Yellow River because of all the desert sands that are yellow that blow into the river and when it floods you get a yellow silt that's going to be 90% of the fertile soil of China and that's why the ancient civilization is going to grow up on the Yellow River or the Huangshi. You could say either one. I'm good with either one, I really am. But at the end of the day we want to understand that China's isolation is going to be really important to their growth in terms of them seeing themselves as the center of the world and also that there's going to be much less trade with the other civilizations. But if you remember anything, remember the power of water. The Huangshi River, the Yellow River in 1887, it flooded, killed like I don't know a million people. That's how powerful it is.
