清晨的第一缕阳光傍晚的第一抹月光
[qīng chén de dì yī lǚ yáng guāng bàng wăn de dì yī mŏ yuè guāng]
Roughly translates to 'the first ray of sunshine in the morning, and the first beam of moonlight in evening'. This implies beauty of natural phenomena, and probably reflects the user cherishes quiet moments or holds poetic sentiments for everyday occurrences and scenery.
