Usage of punctuation marks in titles:

The title of the official document, that is, the end of the first-level title, is generally not punctuated. The internal title of the official document, that is, the end of the second and third-level titles, is generally not punctuated if it is the central title; If so

Shorten the title by two boxes and mark it with serial number (such as 1...2.3, first, second and third), and you can also add a period. The title of the first paragraph in the official document is the title of the first sentence in the natural paragraph of the official document, and the end can be added with a period; If you don't add a period, you can leave a space between the first topic of the paragraph and the document content that follows. Within the official document title, except the title and quotation marks, punctuation should be avoided as far as possible.

For example:

The title of an official document adopted at the Fourth Session of the Seventh the National People's Congress Standing Committee (NPCSC) was "Decision of the NPC Standing Committee on Strengthening Democracy and Legal System, Maintaining Stability and Unity, and Ensuring the Smooth Progress of Reform and Construction". After "strengthening democracy and legal system" and "maintaining stability and unity", there was no pause.
