Han Yi, the Taishi Cheng, believed that the “Ganxiang Calendar” reduced too many divisions of the Big Dipper, and after a period of time, the calculation results would inevitably precede the actual celestial phenomena. Therefore, he created the “Huangchu Calendar”, using 4883 as the counting method and 1205 as the division of the Big Dipper.
