Although they are all called the Zodiac, these twelve animals are different. The zodiac in China is the representative of the twelve earthly branches, namely, rat, ugly cow, silver tiger, hairy rabbit, dragon, snake, afternoon horse, sheep, monkey, chicken, dog and pig. With the passage of time, people gradually associate the zodiac with people's fate and begin to have a strong superstitious color. For example, wear red in the animal year, so that the new year can be prosperous and avoid colliding with bad things.
The Chinese zodiac in Iran is not only less than ours, but also different from the Chinese zodiac. They added leopards and whales to their zodiac signs and deleted dragons and tigers. There is no dragon because it is the totem of the Chinese nation, and there is no dragon in real life. About the appearance of dragons, they are all pieced together by different animals. I have to say that the wisdom and creativity of our ancients are still amazing.
In fact, many countries in the world have zodiac signs. Different countries have different zodiac signs because of different regions and cultures. However, since heavenly stems and earthly branches has been said in China since ancient times, we have combined the Zodiac with the earthly branch, which is not found anywhere except in a few countries influenced by our cultural history. In fact, no matter which country's zodiac signs are, most of them originate from ancestors' worship of animals. At that time, science was not very developed, and people would attribute some things to mysterious forces in their own imagination, and animal worship was a manifestation.
