我们还是孩纸一样年少无知
[wŏ men hái shì hái zhĭ yī yàng nián shăo wú zhī]
This means 'We are Still Children, Naive and Youthful'. It captures the innocence and naivety of young age, indicating an ongoing childlike perspective despite time passed. Often used to reflect back on a less complicated past filled with ignorance.
