《菜根谭·修身》
钟和鼓形体空虚，为了声音的传播而招致敲打撞击；麋和鹿本性喜欢野外奔跑，因贪恋豢养的舒适而被羁绊，失去自由。
钟鼓体虚，为声闻而招击撞；麋鹿性逸，因豢养而受羁縻。
Zhong and Gu forms are hollow in order to convey messages through hitting and knocking, Mi and Lu naturally love running in the wild, but they have been restricted and lost freedom because of the comfort of captivity.
