海枯鱼亡七秒忆永存九命猫死一颗心不灭
[hăi kū yú wáng qī miăo yì yŏng cún jiŭ mìng māo sĭ yī kē xīn bù miè]
With the literal meaning of 'Sea Withered and Fish Drowned Yet a Seven-Second Memory Lasts; Nine-Lives Cat Dead but Heart Unextinguished', this highly poetic name mixes elements from the concept of fish having only 7 seconds memory, the legend of cat's nine lives to express a deeply unforgettable yet painful love or memories that cannot be extinguished even if everything around dies out.
