Once upon a time, the Jade Emperor thought it'd be better to assign an animal to each year so people could more easily remember the Zodiac cycle. So he decided to hold a meeting with all the animals and he would choose 12 of them to be the Zodiac animals. At that time, Cat and Rat were close friends. They were very excited about the meeting and decided to go early. However, Cat was a sleepyhead. He hardly ever woke up before noon. On the night before the meeting, he asked Rat to wake him early the next morning. When morning came, Rat got up early and quietly left for the meeting alone. When Cat finally woke up in afternoon, he knew it was too late. Feeling betrayed, he vowed that henceforth Rat would be his enemy. That is probably the main reason Cats are always chasing after Rats.

Another 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 as 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. So he claimed first place in the competition and the zodiac.

Following closely behind was strong Ox who was named the 2nd animal in the zodiac. After Ox, came Tiger, panting, while explaining to the Jade Emperor how difficult it was to cross the river with the heavy currents pushing it downstream all the time. But with its powerful strength, Tiger made to shore and was named the 3rd animal in the cycle.

Suddenly, from a distance came a thumping sound, and the Rabbit arrived. It explained how it crossed the river: by jumping from one stone to another in a nimble fashion. Halfway through, it almost lost the race but the Rabbit was lucky enough to grab hold of a floating log that later washed him to shore. For that, it became the 4th animal in the Zodiac cycle. Coming in 5th place was the Flying Dragon. Of course, the Jade Emperor was deeply curious as to why a swift flying creature such as the Dragon should fail to reach first place. The mighty Dragon explained that he had to stop and make rain to help all the people and creatures of the earth, and therefore he was held back. Then, on his way to the finish, he saw a little helpless Rabbit clinging onto a log so he did a good deed and gave a puff of breath to the poor creature so that it could land on the shore. The Jade Emperor was very pleased with the actions of the Dragon, and he was added into the zodiac cycle. As soon as he had done so, a galloping sound was heard, and the Horse appeared. Hidden on the Horse's hoof was the Snake, whose sudden appearance gave the Horse a fright, thus making it fall back and giving the Snake the 6th spot, while the Horse placed 7th.

Not long after that, a little distance away, the Goat, Monkey, and Rooster came to the shore. These three creatures helped each other to get to where they are. The Rooster spotted a raft, and took the other two animals with it. Together, the Goat and the Monkey cleared the weeds, tugged and pulled and finally got the raft to the shore. Because of their combined efforts, the Emperor was very pleased and promptly named the Goat as the 8th creature, the Monkey as the 9th, and the Rooster the 10th.

The 11th animal was the Dog. Although he was supposed to be the best swimmer, he could not resist the temptation to play a little longer in the river. Though his explanation for being late was because he needed a good bath after a long spell. For that, he almost didn't make it to finish line. Just as the Jade Emperor was about to call it a day, an oink and squeal was heard from a little Pig. The Pig got hungry during the race, promptly stopped for a feast and then fell asleep. After the nap, the Pig continued the race and was named the 12th animal of the zodiac cycle. The Cat finished as thirteenth place and did not make it in the zodiac.

Another folk story tells that on registration day, the Rat met up with the Ox. He thought to himself 'Ox is the fastest, strongest animal!' So the little Rat played a trick on the Ox. He asked the Ox if he would like to listen to him sing. The Rat opened his mouth but said nothing. 'How was that?' he asked the Ox and of course he replied 'Sorry little Rat, I didn't hear you.' The Rat told the Ox to let him jump onto his back so that he could sing it more clearly, and the Ox agreed. Soon without knowing, the Ox was walking to the signing post, forgetting the Rat on his back. When they reached there, the Rat jumped off and claimed first place. The Ox following and the rest.

Lots of clues (Signs) are embedded in this myth. For instance, the silently singing Rat. It could be a way to try to explain the open mouth of kiore. He is not eating so he must do something else with is mouth:

Ga3-5 (65)

And Hare succeeded by clinging to a log (formed like henua). Scorpio is a mighty time piece up in the night sky. South of the equator Scorpio announces the beginning of summer.
