This pneumatic boulder stands on a steep cliff, 4.37 meters high, 44.47 meters wide, 4.46 meters long and weighs about 200 tons. It has a round top, shaped like a peach, standing on a rock, which lies on the ground and leans towards the sea. The contact surface between the two stones is only 10 square centimeters. The wind blew and the boulder shook gently. If a person lies on his back on a rock with his feet hard, the boulder will shake, but it will not fall down. People standing under the pneumatic stone have a thrilling feeling, sighing as a wonder of the world, hence the name "pneumatic stone", and the poem says: "The wind blows the stone and moves ten thousand horses."

On the pneumatic stone, the words "Three Loyal Ministers of Tongshan: Huang Daozhou, Xie Chen and Chen Shiqi" were inscribed by Lu Zhenfei, the prefect of the Ming Dynasty (1648). On the right side of Panshi, there are four characters inscribed by Xiashan layman in Ming Dynasty, and on the left side, there is a stone tablet inscribed for Cheng Chaojing, the prefect of Ming Navy.

There is also a beautiful legend about wind-driven stones. During the Jiajing period of the Ming Dynasty, pirates invaded Dongshan Island in an attempt to snatch this strange pneumatic stone. They used several warships, put on ropes, and tried to pull hard, but the enemy tried his best and only heard a few "bangs". The rope was completely broken, and the enemies fell into the sea one by one, which was embarrassing. The stone blown by the wind still stands in its place.

Celebrities in the past dynasties sang a lot about pneumatic stones, such as Wen Sanjun's poem in the Ming Dynasty: "Stone is a beautiful space, and it is not the wind that rocks it." The cloud root leads directly to the pagoda, and the moon pavilion is as small as a ladder. "

Therefore, when tourists see this stone, they are always amazed. When they know its beauty, they will take pictures as soon as possible. The windbreak stone is in harmony with the surrounding scenery. No wonder the literati will leave their admiration here: "The scenery here is unique."
