日光倾城未必会温暖夜色孤寂未必会悲伤
[rì guāng qīng chéng wèi bì huì wēn nuăn yè sè gū jì wèi bì huì bēi shāng]
'The sunlight shining on the city doesn't necessarily warm the solitary night; loneliness may not necessarily lead to sorrow.' This implies that even bright moments don't guarantee inner warmth, and being alone doesn’t have to mean sadness.
