鱼的记忆也只有七秒而已猫有九命也只有一心而已
[yú de jì yì yĕ zhĭ yŏu qī miăo ér yĭ māo yŏu jiŭ mìng yĕ zhĭ yŏu yī xīn ér yĭ]
'Fish only remember for seven seconds; cats have nine lives but just one heart'. Combines the common belief that fish only have short-term memories, with cats, traditionally viewed as having multiple lives yet being loyal creatures, reflecting themes of transient memory versus loyalty.
