时光带不走年少轻狂
[shí guāng dài bù zŏu nián shăo qīng kuáng]
Time Can't Take Away Youthful Recklessness - expressing nostalgia for the days when we were young and didn’t know better; those times filled with audacity and carefree attitude that seem to never fade away. There's also underlying belief that despite growing older and changes over time, some aspects like youthful fervor or spirit are timeless and eternal.
