分手只是一时爱你只是一世
[fēn shŏu zhĭ shì yī shí ài nĭ zhĭ shì yī shì]
Translated as 'A breakup lasts only a moment but loving you spans a lifetime.' Here, the person implies that while their relationship has ended ('a moment' referring to a brief point in time), their feelings for their partner will persist forever, reflecting deep and unwavering love.
