In Chinese astrology the animal signs assigned by year represent what others perceive you as being or how you present yourself. It is a common misconception that the animals assigned by year are the only signs and many western descriptions of Chinese astrology draw solely on this system. In fact, there are also animal signs assigned by month (called inner animals), by day (called true animals) and hours (called secret animals).
While a person might appear to be a Dragon because they were born in the year of the Dragon, they might also be a Snake internally, an Ox truly, and a Goat secretively.
A conflict between a person's zodiac sign and how they live is known as tai sui or kai sui.
