For example, the number of strokes of Yoshida-Ji 6, Tian 9, Tian 9;

The number of strokes of Yan-Yan 7, Xiao 3, Lai 13.

Step 2: Rank the number of strokes of two people's names as 6, 9, 9, 7, 3, 13, which is the number on the first floor of the inverted pyramid.

Step 3: Add up the figures on the first floor to get single digits!

For example, 6+9= 15, and one digit is 5; 9+9= 18, with 8 digits; 7+3= 10, take a digit as 0 ... and so on to get a new set of numbers, which is the second series.

Step 4: Calculate the numbers of each layer in turn according to the above method until there are two numbers left at last, then this number plus "%"is the coincidence rate between you.

As shown in the figure, we can calculate that the coincidence rate of Ji and Yan is 72%!

Dear friends, go and try it! Calculate the coincidence rate between you!
