Why is pneumatic stone a stone with solar terms?

The magic lies in its excellent weight balance. When the wind blows, the stone body shakes from side to side, but it won't move again when it is tilted to a certain angle, so it is called pneumatic stone.

On the front of the stone body, Huang Daozhou, a great scholar in Ming Wuyingdian, wrote "Tongshan Pneumatic Stone" with vigorous brushwork. On a square stone tablet in front of the pneumatic stone, there is a poem by Cheng Chaojing, the governor of the Ming Dynasty: "Nature originally made a pill, which sealed the valley in the east. When the wind blew down the customs, Haibiao had to turn gradually. It is difficult for five people to do anything, and one person does not have enough to eat. Who can measure the support of ghosts and gods, the machine of movement should be here. "

Through this poem, we can feel the momentum and integrity of this stone.

"Let him wind and rain, I will stand."
