渲染一世哀愁的情真意切繁华一生悲伤的人情冷暖
[xuàn răn yī shì āi chóu de qíng zhēn yì qiè fán huá yī shēng bēi shāng de rén qíng lĕng nuăn]
The meaning is 'spreading the sorrow over a lifetime with genuine affection and devotion amidst the bustling life's warmth and sadness.' It expresses a deep feeling where one’s life full of prosperity also witnesses the emotional changes from warm relationships to cold indifference.
