The phrase "good pairs make for a good match" comes from traditional Chinese culture and folk beliefs and is used to describe the matching of animals in the zodiac. In traditional Chinese culture, each zodiac sign has its own sayings about supporting and harming each other.
The zodiac signs are arranged according to a 12-year cycle and are rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog, and pig. Therefore, the "good pairs" in "good pairs are combined" mostly refer to zodiac signs that are well paired under the concept of mutual support and compatibility. Generally speaking, dragons and snakes are considered "good pairs" because they are considered to have a good complementary and cooperative relationship in the theory of zodiac signs.
