Di (邸), which literally means the 'subnational government officers' residence in the capital', was instituted to solve the intelligence transmission issues and made it more efficient for the Jun-Xian system.

[2] Historians also doubt the societal and economic conditions in the Han dynasty that if it was powerful enough to support the huge Dibao delivery system among 100 Juns and 1400 Xians because the continuous wars with the northern Xiongnu (匈奴) nomadic nation continuously weakened the national strength of the Han dynasty.

[9] Everything related to the emperor's daily life, such as the important speeches, summons, hunts, religious duties, conferment and award ceremonies would be written by the imperial historians on books and published on Dibao.

[7] In the Song dynasty, legislation became an official part of Dibao that published periodically, which involved the new edicts, penal laws, political decisions from the emperor on the memorial to the throne (Chinese: Zouzhang/奏章).

[10] Kaiyuan Za bao records a memorial to the throne about a new type of grape brought from the western region in the Han dynasty, which was marked as reviewed and commented with 'boring' by the emperor and not allowed to publish on Dibao.

Some memorials to the throne were requested to 'Liuzhong' by the local government as they involved significant national secrets in political and military fields that could not be published to the public.

[10] With the rising political party movements and conflicts, the dynamic of the imperial court and the appointment and dismission of the government officials that published on Dibao gradually became the most significant information source for both the civil officials and military officers to know the occupation demand of the government, understand and analyse the political circumstance of the empire in the Song dynasty.

[12] The content about military action, especially related to the mutiny, peasant revolt, and the minority armed resistance, generally would not be allowed to publish on Dibao because they could disturb the popular mind and destroy the societal stabilisation and harmony, which can threaten the imperial regime and the authority of the ruling class directly.

The imperial court and the emperor did not review and restrict the content written on Dibao because it only represented the Fanzhen governor, which was not the official gazette of the empire.

[10] Dibao in the Song dynasty started to publish the content periodically related to the daily life of the emperor, edicts and political decisions, the dynamic of the imperial court, and the reports of military, diplomacy and natural disaster as a result of the ruling classes attached great importance to the function of Dibao, which aimed to transmit the information, consolidate feudal governance, and protect the rights and interests of the ruling classes.

[2] The loss of the Northern Expedition war led by the emperor Ningzong of Song (宋寧宗) and the imperial military caused huge casualties, which ignited the anger of the public.

A deep self-criticism written by the emperor Ningzong of Song was published on Dibao and delivered to the local governments and shown to the public, which presented the good image of the emperor that aimed to quell the public anger, increase the military morale, and maintain the image of the ruling class.

[9] The emperor in the Qing dynasty became the editor in chief of Dibao who completely controlled and managed the imperial propaganda and public opinion.

[15] The content published on Jingbao only involved the edicts and decisions, which was used as Bulletin Board for the public and foreign ambassadors.
