深海锁心
[shēn hăi suŏ xīn]
'Shen Hai Suo Xin' translates as 'Deep Sea Lock Heart'. Here, deep sea represents mystery, depth, and sometimes isolation. This implies locking one’s heart into depths, either for safekeeping feelings away from the surface or expressing the idea of being isolated and unreachable emotionally, like a hidden treasure in the abyss.
