The principle of determining the written date is: the resolutions and decisions adopted by the meeting shall be based on the date formally adopted by the meeting; The official document issued by the person in charge of the organ shall be subject to the date of issuance; The joint writing shall be based on the date issued by the person in charge of the last issuing authority. There are two kinds of marking positions of the written date in official documents: one is the official document reviewed and approved by the meeting, and the written date is arranged under the title of the official document and enclosed by "()", which is used all year round, month and daily; The second is to mark the date of writing at the lower right of the document text or annex description, and write the year, month and day.

The date of writing is generally arranged in the four words on the right, and the year, month and day are marked with Arabic numerals. The year should be marked with the full name, and the month and day cannot be empty (i.e. 1 no coding is 0 1). For official documents without official seal, the date of writing should be arranged in line 1 under the signature of the issuing authority, and the first word should be moved to the right. If it is longer than the signature of the issuing authority, two words shall be arranged in the right space, and the number of words in the right space of the signature of the issuing authority shall be increased accordingly. When affixing the signer's signature stamp, leave 1 line on the right below the signer's signature stamp to arrange the writing date.
