Kua numbers are used in the application of 8 House feng shui. In some parts of the world, it is also known as 8 Mansions feng shui. But they refer to the same school of thought.

Calculate Kua number for men

Take the birth year and add up the individual numbers until you get a number no larger than 10. Then subtract the resulting number from 11.

Example: Birth year 1975

1+9+7+5=22

2+2=4

11-4=7

Kua number is 7

Since Kua number 5 does not exist, a man will have Kua number 2 if the result from the above formula is 5.

Calculate Kua number for women

Take the birth year and add up the individual numbers until you get a single digit number. Then add 4 to the resulting number.

Example: Birth year 1976

1+9+7+6=23

2+3=5

4+5=9

Kua number is 9

Since Kua number 5 does not exist, a woman will have Kua number 8 if the result from the above formula is 5.

Below are what the Kua number reveals in 8 House feng shui. Do note that SC, TY, YN, FW, JM, LS, WG ,HH, are abbreviations for Chinese words. At a basic level, you just need to know which are good and which are bad.
