《智囊(选录)·闺智部·总序》
月亮要借助日光才能明亮，所以妻子向丈夫行芹，日落之后月光照明，因此女子是男子的辅助，这就是日、月的智慧和才能。
日光而月借，妻所以齐也；日殁而月代，妇所以辅也。此亦日月之智，日月之才也!
The moon relies on the light of the sun to shine, so a wife offers celery to her husband. After sunset, the moonlight brightens, so a woman is an assistant to a man, and this is the wisdom and talent of the sun and the moon.
