倒转流年只为一笑红颜
[dăo zhuăn liú nián zhĭ wéi yī xiào hóng yán]
It means 'reversing years just for the beloved’s smile'. There's a sense of devotion expressed through wishing time reversed just to see the person's beauty again or gain their smile. This carries romantic connotations and reflects the deep adoration one has over their partner's presence.
