时间是嘴上能治百病的庸医
[shí jiān shì zuĭ shàng néng zhì băi bìng de yōng yī]
'Time is a quack doctor who boasts of being able to cure all diseases.' Using a metaphor comparing time to a self-proclaimed physician curing all ailments, this implies that although time does provide solutions and brings relief to many troubles in reality, there also exists a hint of cynicism toward its effectiveness.
