The Chinese zodiac
Chinese scholars began by thinking of the stars, the sun, and the moon as gods. Like the scientists of Mesopotamia, they thought they could use the movements of the stars to predict the future.

Chinese astronomers divided the sky up into zones like Sumerian zodiac signs, but they divided it in different places and assigned different meanings to the stars. Nobody knows for sure whether the Chinese astronomers even knew about the Mesopotamian system.
What are the signs of the Chinese zodiac?
The Chinese zodiac system followed a twelve year cycle, combined with another cycle of five years to make a longer sixty day cycle. (The choice of twelve and sixty, important numbers in Mesopotamia, might show that there’s some relationship there.)
The twelve signs, one for each year, are the rat, ox, tiger, rabbit, dragon, snake, horse, goat, monkey, rooster, dog and pig. The Chinese New Year (in January or February) marks the change from one year to the next.
Chinese New Year
People in China thought a baby would have the character of the Chinese zodiac sign for the year it was born. So a baby born in the Year of the Snake would be deep and complex, calm and observant. But a baby born in the Year of the Goat would be stubborn and generous.
Solar and lunar eclipses
But by the time of the Han Dynasty, about 130 AD, scholars like Zhang Heng knew that the moon was a sphere, lighted by the sun on one side and dark on the side away from the sun. Zhang Heng also understood what caused solar and lunar eclipses.

Can the stars predict the future?
Chinese astronomers, like Roman and Sassanian astronomers of the same time period in Europe and West Asia, were very interested in the stars for scientific reasons, but they also kept on thinking that the skies could help predict the future.
West Asian science
One of these Chinese astronomers drew this star chart, which is the oldest one in the world. Even though telescopes and binoculars hadn’t been invented yet, the chart shows some very faint stars that are very hard to see with just your eyes.
But along with this chart, there were also instructions for predicting the future based on the shape of clouds!
