one day, a crow found a piece of meat. It stood on the tree brench feeling very happy. Then a fox saw the meat in the crow's beak, so the fox started to flatter the crow; wishing the crow would share the meat. The crow did not answer. At last, the fox said,"how beautiful your voice is, please sing a song for me". The crow fell for the trick and said "ok", but as the crow open up it's beak, the meat fell off to the groud. The fox picked up the meat and went home happily.
