For example, according to the Notice of General Offices of the General Office of the Central Committee of the CPC and the State Council on Supervision and Inspection of the Implementation of Document No.8 [2004] and Document No.0/6 (Document No.4 [2006]) and the Notice of General Office of the Ministry of Education on Self-inspection of the Implementation of Document No.8 and Document No.0/6.

The document number consists of the word, year and serial number of the issuing authority. Agency substitution generally includes two levels. The first level is for the issuing authority, and the second level is for the sponsoring department of the issuing authority.

For example, the official characters of the document of the Ministry of Railways are "Tieban" and "Tiecai", where Tieban stands for the Ministry of Railways, and "Banban" and "Caicai" stand for the office department and financial department of the Ministry of Railways that sponsored the document. It is very important to know the nature of the organization, especially who is the sponsor of the document, so as to process, query, save and archive the document more accurately.

For example, in the State Council, there are "Guo Fa" and "Guo Han", with "Guo" representing the State Council, and "Fa" and "Han" representing "the State Council Document" and "the State Council Letter". Some document institutions have as many as seven or eight words or more, which may be at different levels, but it is better to simplify them as much as possible.

The full name of the year should be used, and it cannot be simplified. For example, "87" and "93" are all marked wrong. The year should be enclosed in hexagonal brackets.

Note that hexagonal brackets are not brackets in mathematical formulas, because when quoting official documents, the document number after the title should be enclosed in brackets "()". If the year is enclosed in brackets, it violates the principle that high-level symbols should not be included in low-level symbols. Therefore, it is called "hexagonal bracket" because it is different from brackets in mathematics.
