Name theory holds that a person's name is closely related to their Zodiac. The zodiac refers to the heavenly stems and earthly branches of the year in which a person was born. For example, those born in the year of Jiazi are considered to be of the rat, those born in the year of Yi Chou are considered to be of the ox, those born in Bing Yin are considered to be of the tiger, and so on. Among the twelve zodiac animals, the following pairs are considered compatible: rat and ox, tiger and pig, rabbit and dog, dragon and chicken, snake and monkey, horse and sheep. The following pairs are considered conflicting: rat and horse, ox and sheep, tiger and monkey, rabbit and chicken, dragon and dog, snake and pig. The following pairs are considered harmful: rat and sheep, ox and horse, tiger and snake, rabbit and dragon, monkey and pig, chicken and dog. In names, "conflict" and "harm" are considered bad, while "compatibility" is considered good. Therefore, when choosing a name, one should strive to make the name compatible with the zodiac, avoiding conflicts and harms. How exactly can this be done?
