璧玉 (The first character has the fanqie bi + yi. The Erya says: 'When the solid jade border is twice the width of the central hole, it is called a bi; a bi that is six inches wide is called a xuan.' Guo's commentary says: 'The solid part is the rim; the hole is the hao.' The Baihu tong says: 'The outer roundness models Heaven; the inner square hole models Earth. Rulers hold it as a sign of trust to sacrifice to Heaven.' The second character has the fanqie yu + yu. The Erya says: 'That which is made of jade is called a gui.' The Book of Rites says: 'When holding jade, one does not hurry.' The Canon of Shun says: 'Cultivating the five rituals and five jades.' Kong's commentary says: 'The feudal lords of the five ranks each held their respective jade.' The Baihu tong says: 'Jade models the virtue of the superior man: when dry it is not light, when damp it is not heavy.' The Shuowen jiezi says: 'Jade possesses five virtues').
