Little Shenyang Ji Xiaolan's joke

Ji Xiaolan, as a minister of does, went to visit with Yushi one day. Chatting, suddenly a dog ran outside. Shangshu suddenly had a plan to make fun of Ji Xiaolan and said, "Do you think it was a wolf (assistant minister) or a dog?" Ji Xiaolan knew that Shangshu was playing a trick on him, so he said quietly, "There are two ways to distinguish a dog from a wolf. One is to look at its tail, which is a wolf, and Shang Jian (Shangshu) is a dog. " The imperial censor laughed: "Haha, I don't know if it's a wolf or a dog, Shang Jian is a dog!" " At this time, Ji Xiaolan went on unhurriedly: "Another way to tell is to see what it eats. Wolves don't eat meat, dogs feed meat. " Even this suggestion was suppressed.
