鱼的第七秒是重生猫的第九次是死亡
[yú de dì qī miăo shì zhòng shēng māo de dì jiŭ cì shì sĭ wáng]
The phrase 'A fish rebirths in its seventh second; A cat dies its ninth life' draws from beliefs and folklores where animals are seen as experiencing life uniquely. Fish having only seven seconds memory is a common myth leading to an idea of perpetual rebirth while cats having nine lives is popular, symbolically reflecting different aspects of life and death between creatures.
