心火微燃细雨清寒
[xīn huŏ wēi rán xì yŭ qīng hán]
'A slight spark in the heart under the cold drizzle' illustrates a gentle kindling emotion against a backdrop of a chilly, rainy day. It signifies a faint flicker of hope amidst sorrow; a moment when despite surrounding coolness or adversity, the core remains stirred, warm - hinting perhaps a newfound courage or resolve arising within hardships.
