Matters needing attention

Quoting refers to quoting others' words in writing. Idioms, aphorisms, poems, etc. It also includes onomatopoeic words and transliteration words. Specific appellations refer to names, abbreviations, special terms, anniversaries, etc. with certain characteristics. Words in special meaning indicators have new meanings in their specific language environment.

When using quotations, pay attention to the position of punctuation marks at the end of quotations. Always use the quoted words independently, and put the last dot in quotation marks. If the quoted content is a part of a sentence, that is, the quotation has no independence, and there is no need to use a dot at the end of the quoted part (question mark and exclamation mark can be reserved), and the whole sentence stops at this pause, what dot should be used?
