"Brass bells" refers to costly instruments such as bells and chime stones which ring clear and true. When these are cast aside and a great ruckus is beaten out on earthenware cooking pots (when the wise are ignored and lesser counsel prevails), how can one not lament?
「黃鍾」指的是鐘、磬等能發出標準音的貴重樂器，瓦釜則是陶瓦做的鍋子，當黃鍾被冷落一旁，瓦鍋卻在一旁大鳴大放，怎不令人感嘆？
