深溺他城却不知为何落泪
[shēn nì tā chéng què bù zhī wéi hé luò lèi]
'Deeply submerged in a strange city yet unknown tears fall' conveys a sense of being overwhelmed by the environment around you, to the point where one feels lost and weeps for reasons they don't fully understand. It represents feeling out of place or emotionally vulnerable amidst an unfamiliar or perhaps chaotic setting.
