Empty vessels make the most sound.
空桶响叮当。/肚内没货最会叫。
Well goes the old saying, “Empty vessels make the most sound.” This simply means that people without any brains talk the most, whereas learned people don’t say much. It is the latter that we should model ourselves on.
俗云:“空桶响叮当。”这就是指没头脑的人话最多,而有学问的人则不多言。我们应以后者为榜样。
