Sima Xiangru's son Xu Fu: "Its stone is a ruby rose." Also known as pearls. Urgent articles: "Bibi pearls, rose urn." Yan Shigu's Note: "Roses are also beautiful jade, or the pearls are particularly refined and called roses." On the origin of the name of rose, Shuowen said: "Rose is the beauty of stone, and rose is the circle of beads", that is to say, "Rose" is the most beautiful among jade and "Rose" is the most beautiful among jewelry; There is also a saying in Sima Xiangru's Zi Xu Fu that "its stone is a ruby rose". Even after the rose became the name of the flower, China people did not have such a gentle explanation as westerners. Because there are sharp hedgehogs on the stems of roses, people in China regard them as "aristocrats" and call them "assassins".
