默写这伤感背诵这幸福
[mò xiĕ zhè shāng găn bèi sòng zhè xìng fú]
'Write Silently this Sadness, Recite this Happiness' signifies writing down sad stories quietly and remembering happy memories aloud; it expresses the contrast between sorrowful and blissful experiences and implies keeping these dual aspects of life deeply inside one's heart.
