Song Ti is the most widely used font and can be used in any typesetting. Regular script is different. It usually appears in quotations, titles and explanatory texts of some articles. Details are used in the typesetting of books, often in the text, but the line symbols are even different. They are used in the preface, quotation, comment and text of poetry. We also see more bold words, which are often used as titles or to express important content.
Each font has different forms in different publications, so it is more reliable to find a professional publishing company for personal publishing. They can make a typesetting for you professionally, paying attention to every detail.
