鱼有七秒情唯有一颗心猫有九条命唯有一颗心
[yú yŏu qī miăo qíng wéi yŏu yī kē xīn māo yŏu jiŭ tiáo mìng wéi yŏu yī kē xīn]
'A fish's love only lasts seven seconds and has only one heart; a cat has nine lives but also only one heart.' Through metaphorical use, it suggests a philosophical view that regardless of our differences, we still share common emotions and vulnerabilities.
