白寻
[bái xún]
'白寻' means 'search in vain'. Sometimes we go out searching for something, but no matter how hard we try, we end up finding nothing, leaving our efforts wasted. So the user of this nickname might be conveying his disappointment in doing things futile or in vain in real life. Also it may imply sometimes despite great exertions put in, still failed to get the expected results, or just express a wishful mindset, hoping to find valuable meaning in daily life or experience meaningful moments.
