The attachment title shall be arranged in the center on the third line of the page. The attachment serial number and attachment title shall be consistent with the description of the attachment. The format requirements for attachments are the same as those for the main body. If the attachment cannot be bound together with the main body, the document number shall be arranged in the first line at the top left corner of the attachment, and the word "Attachment" and the attachment serial number shall be marked after it.
7.4 Copyright
7.4.1 Separation lines in the copyright
Separation lines in the copyright should be the same width as the center of the page.

The first separation line is located above the first element in the copyright, and the last separation line coincides with the bottom edge of the center of the page on the last page of the document.

Add a full-width colon and the name of the copy to agency after the word "copy to", and align with the first word after the colon when returning to the line. Put a period after the name of the last copy to agency. If the main agency needs to be moved to the copyright, except that the word "copy to" is changed to "main to", the arrangement method is the same as the copy to agency. When there are both the main addressee and the copy addressee, the main addressee should be placed one line above the copy addressee, without a separator line between them. 7.4.3 Issuing agency and issuing date
The issuing agency and issuing date are generally written in size 4 Fangsong font and are arranged above the last separator line. The issuing agency is left blank and the issuing date is left blank.

The year should be marked in full, and the month and day should not be marked with empty spaces (i.e. 1 is not marked as 01), and the word "issuing" is added at the end.
If there are other elements in the colophon, they should be separated from the issuing agency and issuing date by a thin separator line. 7.5 Page numbers

Single page numbers are right-aligned with one space, and double page numbers are left-aligned with one space.
