Book titles represent the names of books, chapters, newspapers, plays, songs, etc.

1. If there is a title in the title, use a double title outside and a single title inside.

For example:

Thoughts on reading Shi Zhongshan.

2. When the title of the book is used together with the title of the article, write the title of the book first, then the title of the article, add a space symbol in the middle, and then add the title. For example:

"Xunzi? Persuade to learn.

Third, the misuse of the title (the title should be used when using quotation marks)

1, the trade name cannot use the title of the book.

For example:

Haier brand air conditioners have been sold overseas. (The title of the book should be deleted)

2. The ID card doesn't need a title.

For example:

Public security organs are responsible for issuing "identity cards" to citizens. (The title of the book should be deleted)

3. The column name should be put in quotation marks, not in the title. Program titles are available.

For example:

4. Themes, meetings, slogans, etc. You don't need a title, but you can use quotation marks.

(The title is changed to quotation marks)

5, exams, competitions and other activities do not need a title. For example:

People are familiar with the IELTS test, and now the examination center of the Ministry of Personnel has also launched a brand-new professional foreign language proficiency test-BOS BULATS test, also from Britain.

(The two titles in the sentence should be changed to quotation marks)
