In a sentence, when quoting other people's complete sentences or famous sayings, the period should be put in quotation marks, while if quoting part of others' words or famous sayings as part of a complete sentence, the period should be put outside quotation marks. Commas can also be used in this way. There is a saying in Zhu Ziqing's Spring: "Blow your face without cold willows", which is well said, like a mother's hand touching you. This sentence is good except for the quotation marks.
