Where is Gui Feihong's stone?

Guifeihong is a rusty stone in Shandong. Because its color and texture are related to Shandong iron mine, its surface is rusty, so it is named "Rust Stone". The color is similar to that of the imperial concubine. Guifei Redstone is natural in texture and soft in color, giving people a warm and comfortable feeling, so it is widely used in indoor and outdoor decoration.
