What do you mean by counting?

Finger-pinching calculation is actually the highest realm prediction of Yijing: the algorithm of Taoist magic! According to the time of divination or the time of the incident, the ancients calculated the information of heavenly stems and earthly branches's Eight Diagrams, Eight Doors, Nine Palaces, nine planets's Nine Gods, etc.

(1) Most fortune tellers use the phrase "Wait till I squeeze my fingers to calculate". This seems mysterious, but it is actually just a method to calculate heavenly stems and earthly branches: the coordination of the ten heavenly stems and twelve earthly branches generally requires pen and paper, but the ancients rarely had the opportunity to use pen and paper when calculating numerology. So, divide the finger into three sections and fix it for just ten days. When matching with the twelve earthly branches, you need to read the earthly branches according to the knuckles, so that you can quickly calculate the heavenly stems and earthly branches of the year and month, and you can calculate it with a pinch of your finger.

(2) Pinyin: qi ā zh ǐ y and su à n.

Meaning: or use hand index, metaphorically speaking, the number is small. With "one hand counts".
