I just looked it up online and in a dictionary. Three answers came out: 1 满瓶不响，半瓶响叮当--not direct, but similar. 2 空桶响叮当 --a direct and vivid translation for it. 3 无知的人叫得最欢 --reveals more mockery All are authentic in Mandarin. Personally, I prefer the third one, for it is amusing and easy to understand. But to be honest, I myself rarely use this proverb.
