看彼岸花开不过一季在隔岸观火不过一时
[kàn bĭ àn huā kāi bù guò yī jì zài gé àn guān huŏ bù guò yī shí]
Metaphorically observing situations from afar like flowers only bloom for a short season, suggesting temporary excitement or interest without getting directly involved, symbolizing the fleeting nature of events outside oneself.
