The pot called the kettle black.
五十步笑百步。
We have no right to criticize others for behaving in the same way as we do ourselves. As the saying puts it, “The pot called the kettle black.” Therefore, one needs to look at oneself before making any comments about others.
我们无权批评举止与我们一样的人。有道是:“五十步笑百步。”因此,我们在评论别人之前必须先自省一番。
