Is the printing style in Song Dynasty regular script, imitation song style or song style?

Songti is a Chinese font that seems suitable for printing. The strokes vary in thickness, generally horizontal and vertical, with decorative parts at the end (namely "feet" or "serif"), and strokes such as dots, strokes, strokes and hooks have sharp points, which belong to white body and are often used for text typesetting of books, magazines and newspapers. Because it was introduced to Japan from the Ming Dynasty, it is also called Ming style and Ming style. Song style is a printing form, which was born in block printing and formed in Ming Dynasty. In recent years, there are rumors that it was created by Qin Gui, which is groundless, neither recorded in historical materials nor supported by literature. However, in the existing literature, it can be clearly found that imitation of Song Dynasty and Song Style were both formed in the bookstore. After the Song Dynasty was defeated by the Jin Dynasty, people thought that the books left by the Northern Song Dynasty were reprinted. Many publishing houses were established on Pengbei Street in Lin 'an, the capital of the Southern Song Dynasty, including Chenzhai Bookstore in Chen Qi. The books published by Chenzhai Bookstore have distinctive regular script fonts. This kind of font, copied by later generations, is the so-called "imitation of Song Dynasty" in modern times, which has become the basis of Songti characters.
