冷暖自知情海勿近
[lĕng nuăn zì zhī qíng hăi wù jìn]
'Knowing Warmth and Coldness Alone, One Must Keep Clear of Sentimental Sea.' It means everyone has their unique feelings within hearts; one needs to understand joys and sorrows independently without getting entangled into complex sentiments too much. The phrase warns against immersing oneself deeply into overly passionate or chaotic situations. This kind of username often embodies experiences related to heartbreak or emotional disillusionment in romantic contexts.
