鱼忘七秒你可知
[yú wàng qī miăo nĭ kĕ zhī]
This name draws from the popular belief that fish have a 7-second memory. It symbolizes fleeting memory or the tendency to easily forget. The latter part 'you ke zhi' asks 'do you know'. So, this internet name can mean 'Do you know the feelings of forgetting things as quickly as a fish? Or how I can so easily be forgotten by others just like fish forget things.'
