The questioning after the autumn is the embodiment of conforming to heaven. In ancient China, it attached great importance to the cycle of justice, especially on the issue of life and death. Even criminals generally believe that summer and spring are a period of renaissance and vigorous new life, and it is not suitable for taking people's lives. Moreover, the educational significance produced by the implementation at this time is not as good as that in autumn and winter, when the cold wind blows, the cold atmosphere is relatively sufficient. In this period, God will not blame the execution, which is regarded as doing justice for heaven. According to historical records, customized execution after autumn came into being in Ming and Qing Dynasties, especially during Shunzhi period of Qing Dynasty. From the perspective of hearing cases, it can also avoid the occurrence of unjust, false and wrong cases to the greatest extent and give prisoners greater vitality than court trials. After all, some cases can be dealt with leniently through other channels. For example, during the Yongzheng period of the Qing Dynasty, the emperor directly issued a decree called "raising children and bearing sacrifices". If the prisoner is the only child in the family and his parents or grandparents are still alive, then the original death sentence can be approved by the emperor, changed to a heavy stick, and displayed for three months, and the death penalty can be avoided. The second time, after the autumn, it is better to let the masses "lead by example", because autumn is the season when people are idle, and officials can conveniently call the people to the execution ground to watch, which can play a deterrent role, better maintain social stability and public order, and play a preventive role. If it is implemented in spring, the effect will be greatly reduced. After all, all the people are working in the fields at this time, and no one is idle to watch.
