时光你告诉我剩几年能幼稚
[shí guāng nĭ gào sù wŏ shèng jĭ nián néng yòu zhì]
Translating roughly to 'time, please tell me how many more years can I stay naive?', this indicates nostalgia for childhood innocence. It reflects on lost purity with bittersweet feelings as time progresses inevitably. There's also hope for retaining youthful simplicity even when faced with reality and aging process.
