一封信笺叙心事
[yī fēng xìn jiān xù xīn shì]
Translated as 'Xìn Jiān Sù Xīnshì' or 'Expressing Feelings Through A Letter,' this online identity may suggest a preference for conveying thoughts and emotions via heartfelt written words rather than spoken dialogue, reflecting on how people used to correspond through letters when communication was more intimate.
