An ancient folk story tells that Cat and Rat were the worst swimmers in the animal kingdom. Although they were poor swimmers, they were both quite intelligent. To get to the meeting called by the Jade Emperor, they had to cross a river to reach the meeting place. The Jade Emperor had also decreed that the years on the calendar would be named for each animal in the order they arrived to the meeting. Cat and Rat decided that the best and fastest way to cross the river was to hop on the back of Ox. Ox, being naïve and good-natured, agreed to carry them both across. Midway across the river, Rat pushed Cat into the water. Then as Ox neared the other side of the river, Rat jumped ahead and reached the shore first, claiming first place in the competition and the zodiac.
