The "Zhan Guo Ce" mentions the high quality of southern swords and their ability to cleave through oxen, horses, bowls, and basins, but would shatter if used on a pillar or rock. Wu and Yue swords were highly valued and those who owned them would hardly ever use them for fear of damage, however in Wu and Yue these swords were commonplace and treated with less reverence. The "Yuejue shu" (Record of Precious Swords) mentions several named swords: Zhanlu (Black), Haocao (Bravery), Juque (Great Destroyer), Lutan (Dew Platform), Chunjun (Purity), Shengxie (Victor over Evil), Yuchang (Fish-belly), Longyuan (Dragon Gulf), Taie (Great Riverbank), and Gongbu (Artisanal Display). Many of these were made by the Yue swordsmith Ou Yezi.
