鱼忘七秒人忘七旬

'Fish forget in seven seconds, people forget after seventy years.' This name compares human memories with the widely believed idea that fish have only seven-second memory spans. It conveys the sentiment of fleeting memory, implying a life experience where both human and nature share brief recollections. The speaker implies that they can be as likely to forget something as quickly or it may last for an extremely long time, such as seven decades. There’s often a hint of philosophical sadness.
