Q: Why is that strange stone on Dongshan Island in Fujian called "pneumatic stone" and "pneumatic stone"?

The pneumatic stone of Dongshan Island stands by the sea. In the past, when it was windy, you could hear rocks shaking and swaying. If several people push together, the stone will shake and sway. When I was a child, I pushed it with adults as if I could push it down. It used to be interesting, but now that the scenic spots are protected, I won't let it go.

According to legend, when the Japanese invaded China, the Japanese used warships to pull down the wind stone, but the rope was broken and could not be pulled down. It's weird.

The address scientist said that after weathering, a whole stone forms a matching principle similar to that of a door shaft and a door mortar, so the wind will move but not fall, but after decades of severe weathering, it may eventually fall.
