Sitting system began in Zhou, Spring and Autumn Period and Warring States Period. By the time Shang Yang's political reform formally established Qin State, the social organization of Qin State was already quite strict. Shang Yang's political reform established a "joint seat system", including: it is forbidden for father and son to share the same room, and citizens with more than two men must be separated and independently compiled. At the same time, the national government and people are organized according to military organizations. Why are there five families? Do not act without authorization, supervise each other and report to each other. If it is not exposed, ten families will sit together.
Baojia system is a household registration management system with military management since the Song Dynasty. Baojia system was a long-standing social ruling means in China feudal dynasty. Its most essential feature is that "family" is the basic unit of social organization, which is different from the western individual unit.
The Ministry of the Interior of the National Government has promulgated a special interim measure for joint seating, the main content of which is: when joint seating is issued, it shall be signed and sealed by the head of the household or deposited in duplicate in the county and the sub-balance area. If each household finds that another family is a bandit, knows bandits, or harbors bandits, it should report it immediately. If you don't report it, you will be punished with "the crime of shielding" or "the crime of longitudinal bandits".
After the Anti-Japanese War, the National Government revised the above-mentioned giving method in the plan of sorting out the commercial provinces and counties in Sichuan and Guizhou, and changed it to sitting without knot. In other words, every household does not need to sign an affidavit, but if the residents in A are "bandits" or "bandits", once the judicial authorities find out, the residents in the same A will be punished immediately.
