If the quotation is complete and independent, the final punctuation mark shall be quoted and placed within quotation marks.

If the words in quotation marks are only one component of the sentence, the final punctuation mark is not quoted; if the whole sentence needs to be placed here with a comma or period outside the quotation marks; if no pause is needed, no punctuation mark is used.

Example: "Is it because of seeking profit" is a portrayal of his noble character.

As the saying goes, "Dare to be the same but not different", we must have this spirit.

Be careful when using quotations:

Pay attention to the position of the punctuation at the end of the quotation. Whenever quoted words are used independently, the final period must be placed inside the quotation marks.

If the content of the quotation is an integral part of the sentence, that is, the quotation is not independent, there is no need for a period at the end of the quotation (question marks and exclamation marks can be retained), and the entire sentence pauses where it should. What period should be used? What dot number should be used for the number?
