According to the Kangxi Dictionary, the number of strokes of the character "媗" should be 12 strokes; why you mentioned that when you look up the word "媗" online and use "0" to calculate its five-element attribute as "water" ", I don't understand either! But I think this is a wrong inference!
As far as I know, in order to be able to analyze the good and bad luck of a name through the grid, we must first establish the five elements of the name's five grids (heaven grid, personality, ground grid, outer grid, and general grid). This requires the use of Chinese characters. Each Chinese character is composed of basic stroke numbers. The specific numbers of these strokes are called Five Elements Mathematics! However, Five Elements Mathematics only calculates numbers from 1 to 10. For the excess, tens digits are removed, leaving only single digits, and the numbers are reduced to 1 to 10. If the number is 0, it is counted as 10. Then divide these ten numbers according to the five elements of gold, wood, water, fire and earth. Every two numbers belong to a five-element mathematical theory. That is: 1 and 2 are wood; 3 and 4 are fire; 5 and 6 are earth; 7 and 8 are gold; 9 and 10 are water; therefore, the strokes of the character "媗" are 12, then 12-10=2 , then this character should belong to "wood"! The above opinions are for your reference!
