Daphne odora is a very precious wood since ancient times, and it is also the best raw material for making handicrafts. During the Ming and Qing Dynasties, the royal family of the court advocated making all kinds of learning tools with this kind of wood, and the craft was fine, just like the rhinoceros horn. Because Daphne is precious and rich in rotten wood, there are few excellent materials for carving with it. Therefore, in the auction market, once there are large items made by Daphne, there will often be surprising performances. Ancient books have long recorded that Hainan is rich in high-quality agarwood. In the Song Dynasty, Hainan Aquilaria sinensis gradually became a commodity from the imperial tribute, and the trend of over-exploitation became more and more fierce, "millions of dollars".
