下雨天所有阳光扑向黑暗
[xià yŭ tiān suŏ yŏu yáng guāng pū xiàng hēi àn]
Translated as 'On a rainy day, all sunshine rushes towards darkness'. This conveys a melancholic mood, possibly indicating that despite good times (sunshine), the present sadness (rainy day) makes these positive memories seem out of reach.
