What is joint computing?

1, (one index = one index) "one index" is mostly used by fortune tellers. This seems mysterious, but it is actually just a method to calculate the heavenly stems and earthly branches: the coordination of the ten heavenly stems and twelve earthly branches generally requires paper and pencil, but the ancients rarely had the opportunity to use paper and pencil when calculating numerology. So divide your finger into three sections and fix it for ten days. When it matches the twelve earthly branches, you need to read the earthly branches according to your knuckles, so that you can quickly calculate the heavenly stems and earthly branches of the year and month, and you can get it when you pinch your finger.

2. (Analysis) In ancient times, the calculation of numerology was generally based on the coordination of 10 heavenly stems and 12 earthly branches, which generally required paper and pencil, but the ancients rarely had the opportunity to use paper and pencil when calculating numerology. So divide your fingers into three sections, just fix them for twelve days, and read the earthly branches according to your knuckles when matching them, so that you can calculate the heavenly stems and earthly branches of the year and month more quickly.
