There was a rich man who occasionally got two little wolves to keep with his domestic dog and get along well with it. Although it is a little big, it is still very docile. I forgot it was a wolf. One day, lying in the living room, I heard a group of dogs whining and making angry cries. I woke up and looked around. No one was there. Once again, the pillow was ready to sleep, and the dog roared as before, so (he) pretended to sleep and waited (to observe the situation). The two wolves waited until he didn't notice and tried to bite his throat. The dog stopped them from advancing. Kill (a wolf) and take its skin. This is what my cousin Yu Dun said.

Wolf ambition, (yes) really (and) no slander (them)!

Common sense: a leopard cannot change his spots. In essence, ambition is unique to people.
