牵不了的手就不要牵了留不住的心就不要留了
[qiān bù le de shŏu jiù bù yào qiān le liú bù zhù de xīn jiù bù yào liú le]
When translated, this becomes don't hold hands if they can't be held; don't keep hearts that cannot be kept. This is likely reflecting feelings post-breakup, expressing abandonment and letting go, as well as advising against forcing a non-functioning relationship.
