Introduction to Jianhuo Rock: The walls here stand like a screen, and the surrounding stone peaks confront each other, as if they were cut by a sharp sword, hence the name. According to legend, Emperor Zhenwu struck this place with a sharp sword when he saw that the people here were blocked by mountains and could not pass. There is usually no wind at the foot of the mountain, but the wind here can reach level 5 or 6, making it a holy place to cool off.
