The influence of a name on a person is the power of "number" and "sound". A name becomes significant when a person uses it or is called by it; an ominous name brings misfortune, while a auspicious name leads to good fortune. As the ancients said: "Giving a child a thousand pieces of gold is not as good as teaching them a skill; teaching them a skill is not as good as giving them a good name." This shows the importance of a name. A person's name can be chosen through deliberate means, meaning it is the part that can be changed in one's destiny. A person's birth time and date (Eight Characters) are innate, and no one can change them throughout their life. The Eight Characters are like the body, and the name is like the spirit. A name can make up for deficiencies in one’s Eight Characters, and can control and transform unfavorable elements. Therefore, whether a name is good or bad has a great impact on a person's life.
