The Golden Armor General: The Golden Armor Subdues the Black Dragon

In the Taihang Mountains, in northern Henan, there is a peak more than eight hundred meters high. On the mountain is a cave about four or five meters deep. A stone on its wall looks like both a dragon and a python. From the tip of its head, water seeps out drop by drop, exactly once every second. Since the stone is also somewhat black in color, the local villagers named the cave Black Dragon Cave and the mountain Black Dragon Mountain.
