青春是一首笑忘歌
[qīng chūn shì yī shŏu xiào wàng gē]
'Youth Is a Laughter-Forgotten Song' romanticizes youth as an unforgettable tune that can both inspire laughter and evoke bittersweet recollections as we mature and grow older. The song aspect also infers that while it can be revisited and appreciated, like old tunes, it can also bring smiles even when forgotten.
