Please standardize the use of full-width characters to avoid errors in the article to the greatest extent. You may have noticed that there are a lot of "////" strangely appearing in some texts, which cannot be removed. This is exactly the use of half-width single quotes, causing the system to save itself. So, please avoid using half-width symbols, especially quotation marks. How to switch between full-width and half-width depends on the input method you use. Please do your own research or ask someone to help solve it.
