青春是我们仅剩的资本
[qīng chūn shì wŏ men jĭn shèng de zī bĕn]
'Youth Is The Only Remaining Capital' suggests an individual sees youth as a kind of capital - a valuable, irreplaceable asset and believes the youthful days are the final assets people possess before adulthood. After those teenage years end completely with no more left behind then, it'll leave individuals with regret because those fleeting youthful opportunities had already passed away.
