Golden Doctrine, named after metallic characters, implies that children are strong-willed, have strong self-esteem, respect the good and discard the evil, and everything is logical. Be resolute and decisive, be generous with money, and know the shame. If the namers are short of gold in numerology, they can make up for the weakness of numerology and play a role in balancing numerology. If numerology is short of water, they can also be named with the Chinese characters of the five elements of gold, because the five elements of gold produce water. However, if the namers are prosperous in numerology, or if the eight characters are happy with gold, they should not be named with the Chinese characters of the five elements of gold, which violates numerology and cannot achieve a balance in mission. That is to say, people who are happy with the eight characters are fire or big, and it is not appropriate to use the word "Shuo" to name them. Of course, the early stage should be considered in combination with the zodiac, the eight characters, the gender, the surname and the matching words.
