眼角的皱纹那是曾经的微笑
[yăn jiăo de zhòu wén nèi shì céng jīng de wēi xiào]
The wrinkles at the corner of the eyes are signs of past smiles, suggesting this netname is about nostalgia. Life experiences can be seen in one's smile; those smiles may become wrinkles over time, leaving marks of happiness and life's events.
