容嬷嬷拿针扎小三
[róng mā mā ná zhēn zhā xiăo sān]
From the famous Chinese TV drama 'Empresses in the Palace', Rong MoMo is an elderly female character well-known for being loyal but somewhat violent in discipline. The phrase humorously imagines her stabbing someone considered as 'the other woman', suggesting jealousy or punishment against betrayal, especially in a marriage scenario.
