Knuckle fortune telling

Fortune tellers always count with their fingers. What is that? What do you mean?

Taking the joint between the ring finger and the palm as the reference point, counting from the left, the middle finger, the index finger and the palm are connected with one point each, and the joint between the two joints of the index finger, the fingertip of the ring finger and the little finger, and the connection point between the little finger and the palm is twelve o'clock, which means that Ugly did not apply for twelve branches at noon.

Fortune-tellers tend to squint and mumble when counting their fingers, while the hand index is recorded in heavenly stems and earthly branches for years, months and days.
