水还不是会变成眼泪流出来
[shuĭ hái bù shì huì biàn chéng yăn lèi liú chū lái]
Water turns into tears when someone cries which illustrates inner sadness through physical phenomena; it connects external fluid like rain or seawater with human sentimentality by comparing them both as water shedding outwards from eyes due to intense feelings inside heart or mind such as missing, sorrow, etc. This phrase conveys the sentiment that just as water naturally flows downward, so do tears inevitably surface amid emotional distress. The comparison implies the inevitability and authenticity of emotional expressions.
