Introduction to Lunatone.

According to legend, about 65 million years ago, at the end of Cretaceous, a special meteorite hit the mountainous area of the ancient Sishui River Basin in China, and it exploded after hitting the surface rock. In the environment of high temperature, high pressure and plasma, a large number of metal elements and trace elements in interstellar matter are mixed and infiltrated with surface rocks, and fall to the surface during rapid cooling, forming pumice. Because it is located in the Surabaya River basin, it is called the pumice in Sibin, and because meteorites are like beads, the locals call it Yueshi. Four-shore pumice and four-Lunatone refer to the same kind of stone which is formed by secondary variation and is most suitable for making sideboards. The bian stone made of this kind of stone is the traditional bian stone recorded in ancient books such as Huangdi Neijing and Daoshi. Therefore, Sibin Bian Shi and April Bian Shi are the same stone, but the former is the scientific name, while the latter is the folk name of the place of origin. "History of Taoism" records that "Fuxi tasted grass to cure people". "Su Wen Bao Quan Ming Xing Lun" says: "Woo means to treat the gods, cultivate one's morality, know that poison is true, control the size of stones, and know the diagnosis of storing blood and gas in fu organs. Stone here refers to stone, a medical tool made of stone. It shows that bian stone is a kind of stone medical care tool with different shapes, sizes and usage methods, and different shapes of bian stone will be selected according to different diseases (stoves) and uses.
