输了做美人鱼永远劈不了腿
[shū le zuò mĕi rén yú yŏng yuăn pī bù le tuĭ]
The phrase 'A mermaid who can never be unfaithful because she has a fish tail' suggests a unique concept where the person, if defeated in life, imagines becoming a mermaid that cannot engage in infidelity, symbolizing loyalty and uniqueness.
