铅笔画依然是黑色乀
[qiān bĭ huà yī rán shì hēi sè fú]
The net name 'The pencil sketch remains black' seems to emphasize that no matter how much time has changed, some essential and unchanging things still remain, similar to pencil sketches that never fade in color. It implies a person cherishes pureness and authenticity even as the world moves at fast pace.
