深海溺亡旧人心
[shēn hăi nì wáng jiù rén xīn]
'Shen Hai Ni Wang Jiu Ren Xin' means 'the heart of an old lover who drowned in the depths of the ocean.' This indicates lost love that sank to the bottom, forgotten like a tragic tale buried in a deep sea, symbolizing profound regret over failed relationships and memories left behind in the past.
