十字街头苦等的挽留
[shí zì jiē tóu kŭ dĕng de wăn liú]
This phrase can be described as 'holding on while waiting in agony on the crossroads'. Implies a poignant scene where a user is desperately trying to retain or reconcile someone/something, despite circumstances not seeming to favor that, at crucial points in life when paths diverge.
