In history, it is regarded by the world as a beautiful stone after jade. Trionyx sinensis has been regarded as a kind of treasure in ancient China, and its use in China has a long history. The appearance and value of the tortoise shell are described in the historical document "The Ancestors from Outside the Ridge" written by Nan Zongzhou. There are tortoise shells in the South China Sea, which are as big as three feet, and some are less than one foot, but they are very beautiful. In the Three Kingdoms period, Cao Pi, the Emperor of Wei Wen, mentioned in the Preface of Chequ Fu: "Chequ, jade is also a genus, and there are many fibers to manage the text.
