喻道德自古就有“君子比德于玉”的传说,所以“古之君子佩玉”、“君子无故,玉不击”(《礼记·玉藻》),佩玉成了君子有德的象征。 Since ancient times, ethics of morality has been described as “the gentleman is more virtuous than jade”, so Peiyu became the symbol of a gentleman’s virtue with his “old gentleman wearing jade” and “gentleman without cause and jade not falling off” (“Book of Rites, jade algae”).
