我心似海无人力挽狂澜
[wŏ xīn sì hăi wú rén lì wăn kuáng lán]
Literally, it means 'My heart is like the sea with no one can stem the tide.' It reflects a profound and complex sentiment, expressing that one's inner world is deep and boundless just like the sea, while feeling isolated and powerless to change certain outcomes or situations in life.
