The word "rose" can be traced back to Han Feizi's ancient book "Buy a Gift and Return the Pearl" in the Warring States Period. The wooden box in the story is decorated with roses. Roses here refer to charming gems. In addition, according to the ancient word-making rules, it can be proved that the rose was not a flower name at first, but a gem name.
The word "Mei" can be divided into jade and jade, which means jade is radiant. The word "rose" can be divided into jade and ghost, which means fantastic shape. Then, the rose should refer to an unusual and radiant beautiful gem, which is called "Hotch". According to Yao Cha and Yao Silian's "Liang Shu Zhu Yi Biography of Tian Zhong Zhu Guo" in the Tang Dynasty, "Fire is like mica, color is like purple and gold, and it is brilliant."
