Tian Ma | Sky Horse

《The Classic of Mountains and Seas》

From there, 200 mils to the northeast, and you will reach Mount Macheng. It has an abundance of colorful stones, and on its shaded slopes, there are many precious metals and jade. There is a beast there that looks like a white dog with a black head, and it flies when it sees people. It's called the Tian Ma(Sky Horse), and its call sounds like it's calling its own name.
