3. Special circumstances
When the quotation is complete and there are question marks and exclamation marks at the end of the sentence, the question marks and exclamation marks are usually kept within the quotation marks even if they are not used independently.
Example 11 Su Shi raised the question "When will the bright moon come out?" at the beginning.
When expressions such as "so-and-so said" and "so-and-so said" are inserted in the middle of the quotation, although the two quotations before and after may not be complete when viewed separately, the ends of the two paragraphs should usually be kept within quotation marks. (Also note that at this time, a comma should be used instead of a colon after "so-and-so said" and "so-and-so said").
Example 12 “Thousands of sails are passing by the side of the sunken boat,” he recited, “and thousands of spring trees are in front of the diseased tree.
