寶輅（上博抱反切韻珍也瑞也亦賝也禮記云地不藏寶也古文作珤從玉缶聲下洛故反即大輅也案五輅隨飾為名以寶飾曰寶輅也）。

寶輅 (The first character has the fanqie 博抱 [bǎo]. The Qieyun states: 'Precious; auspicious; also treasure.' The Liji states: 'The earth does not hide its treasures.' The ancient script writes it as 珤, derived from 玉 with 缶 as phonetic. The second character has the fanqie 洛故 [lù], which is the imperial great carriage. On examination, the five carriages are named according to their decorations; being decorated with gems, it is called the jeweled carriage.).
