At that time, xi pendants were usually made as pairs and buried in tombs. While the examples dated to the Spring and Autumn period resembled the shape of an animal's tooth or fang, the pendants made during the Warring States period were usually more slender in form. Dragon-shaped pendants were developed from the late Warring States period to early Western Han dynasty; see Gu Fang, The Pictorial Handbook of Ancient Chinese Jades, Beijing, 2007, p.240.
