菊花不狠地位不稳
[jú huā bù hĕn dì wèi bù wĕn]
A humorous and vulgar reference implying that unless you're assertive enough ('unmerciful'), your social standing will waver. Here, 'chrysanthemum' is used in place of a more offensive word. It's a metaphor for needing a certain level of harshness to maintain authority.
