Qiuci's divination in Historical Records Biography of Qiuci and Xu Hu's detailed investigation of divination in the early Qing Dynasty are quite detailed.

A kind of divination. Divination and divination are two earliest mathematical activities in the history of China.

The earliest divination materials in history are Oracle Bone Inscriptions or divination symbols carved on it in Shang and Zhou Dynasties. At that time, before deciding on important matters, people burned tortoise shells or the shoulder blades of cattle, and inferred the good or ill luck of personnel according to the cracks burned. This profession was called turtle divination in ancient times.

The tortoise divination method has been lost for a long time, all because of the evil tortoise divination or the local tortoise not producing turtles.

"The way to attack the tortoise is to remove its armor and keep its wall." There is a straight line from bottom to top in the middle of the tortoise shell, which is called "a thousand miles". There are five horizontal lines, and the blank between the three stripe lines in the middle can be outlined. Oriental A, B, C and Western D, with two walls in the middle, say that waist gold comes first, and those with straight lines above waist gold say that they are soaring to the sky, and whoever only occupies this side will be tested.

Mix one or two pieces of carbon powder and lead powder with San Qian, and mix them with jujube paste to form a block, which is as thick as a rib and 34 minutes long. It is called Sanyi Pill.

The method of burning turtle must be complete in five elements, with water in the bowl, money in it and a ruler on it, and then the turtle shell, with the lettering down and the meat up, burned with Sany Pill. After burning the turtle, the turtle shell exploded loudly, called turtle language. Then sprinkle water on the lettering place, cracks will inevitably appear, and good or bad luck can be judged according to the transverse and longitudinal directions of the cracks. Then wrap a rope around the crack to provide incense to it.

Three days later, the cracks regrouped. If there is still sound in the turtle shell within three days, it is still unfinished and must be reoccupied.
