时光给相爱取名叫放手苍老为青春提名叫流逝
[shí guāng jĭ xiāng ài qŭ míng jiào fàng shŏu cāng lăo wéi qīng chūn tí míng jiào liú shì]
Expresses a bittersweet feeling about love and time. Love is renamed as 'letting go' over time, while aging renames youthfulness as 'the past flowing by'. It's about how love may fade and how youth is transient.
