久留不走只是个笑话
[jiŭ liú bù zŏu zhĭ shì gè xiào huà]
'Staying too long and refusing to leave only makes a mockery of oneself'. Reflecting the sentiment that overextending one's welcome becomes more of a joke or farce. It carries a somewhat resigned and bitter-sweet meaning, acknowledging prolonged efforts or stays leading nowhere eventually turn futile, turning the person into the butt of their story.
