1. Judgment of the five elements: 1. Check the ten thousand years calendar to know the eight characters (use five rats to escape the sun to determine the time);
2. The attributes of the heavenly stems: A and B belong to wood, Bing and D belong to fire, Wu and Ji belongs to earth, Gengxin belongs to metal, Rengui belongs to water;
3. Earthly branch attributes: Haizi belongs to water, Yinmao belongs to wood, Wuwei belongs to fire, Shenyou belongs to metal, Chenxuchou does not belong to earth. ;
4. The five elements are in harmony with each other: wood, fire, earth, metal, water, and wood; the five elements are in conflict with each other: wood, earth, water, fire, metal, and wood.
2. Look at the fortune combination and the missing five elements: check the numerology with the day stem as the main one (this requires professionals), and decide how to make up for it the day after tomorrow.
3. Name: Name according to the situation where the five elements are missing or need to be remedied. The name of the person who needs to replenish water must have the radical character "water" and the other five characters.
The same applies.
