< p > Qin Dynasty < < a href= > http:// > m.pmae.cn/news/index_c.asp > > < < /a > > stipulates that "to pass books and receive books must be written to the sun and the moon."

That is to say, it is necessary to write a clear time for the originating and sending and receiving of documents. Officials who supervise official documents must comply with the relevant regulations. They are not allowed to lend or write "secretaries" without authorization.

< p > in ancient China, < a href= "http:// m.pmae.cn/news/index_c.asp" > confidentiality work < /a > the most stringent decision making agencies are the important central administrative organs such as Shang Shu and Zhong Shu.

The staff of these key secrecy units must be kept confidential regardless of the size of their posts.

Such as Kong Guang, Minister of the Han Dynasty, Minister of the Shang Dynasty and Dr. Yushi, he was cautious and strict in keeping secrets.

"Greenhouse" is the office place of the Han Dynasty where the book of letters is located, which means that even if Kong Guang planted trees on the other side of the greenhouse, he would not go home.

Kong Guang's performance became a model for ancient public officers to strictly observe occupational secrets.

< p > the Qing Dynasty's secrecy system is the most important in the past dynasties, for example, in the Han Dynasty, on the basis of "sealing things", the "secret play" (sealed memorial system) was created.

As the Central Military agency, the Secretary (Zhang Jing) is not allowed to recruit high school children, and the deaf are illiterate.

Irrelevant personnel are not allowed to approach the military office at all.

Only when he went to the warplanes to listen to the instructions and see the memorials, "Fang had to stand upright in the curtain of the military aircraft hall".

< p > > a href= "http://? m.pmae.cn/news/index_c.asp" > confidential document < /a > only for emperors and players.

In the imperial palace of the Qing Dynasty, there was a special office to receive the memorial to the emperor, and officials could not inquire about the contents of the memorial and Chu batch.

In the Qing Dynasty, Chu Zhu's memorials were carried out, and individuals were not allowed to remain and copy privately.

< /p >

< p > most worthy of affirmation is that the ancient emperors will take the initiative to shoulder the responsibility of confidentiality.

Take the Qing Dynasty emperors as an example, all confidential content memorials, such as confidential reports of local governors to subordinate officials for political affairs, are forbidden to be processed unless they are very special.

If the court sends the memo to the relevant departments, it will delete the part of the batch, and sometimes delete the name of the player.
