深海久溺要亡深沉溺海未亡
[shēn hăi jiŭ nì yào wáng shēn chén nì hăi wèi wáng]
'long drowning in the deep sea should die but still alive after deeply immersed in the ocean.' It symbolizes a person enduring long-term hardships like drowning in the sea, who although feels they would never survive such adversity remains tenaciously holding on to life.
