The so-called "Song Style" is a common printing font in China, not a calligraphy font. This font was neither created by Qin Gui nor written by any calligrapher, but created by ancient China calligraphers. Song style is characterized by square font, horizontal and vertical strokes, thin and vertical strokes, and prominent triangular sharp corners in the upper right corner of horizontal painting and horizontal folding angle. Nowadays, the fonts used in books, periodicals and newspapers are mostly Song fonts.
China's ancient books were originally copied by calligraphers. Since the Tang dynasty, there have been woodcut books, but the number of woodcut books at that time was very small. During the Northern Song Dynasty, woodblock printing developed rapidly and gradually formed an atmosphere. In ancient times, there were roughly two kinds of fonts. One is written by calligraphers, and seal engravers engrave books according to the words written by calligraphers. This kind of book is called Writing Prints. For example, Jin Nong's Winter Heart Collection and Banqiao Collection in Zheng Xie. It is very difficult and laborious to carve every word of a book vividly from beginning to end, so most of the fonts on the lettering are carved by the engraver according to the standard font. The standard fonts for engraving books in different times also have different characteristics.
There are two kinds of fonts in Song Dynasty, fat and thin, which absorb some characteristics of European, Yan and Liu Kai-shu fonts and make them artistic and standardized. It becomes a square or rectangular lettering font with even horizontal and vertical strokes, which is similar to the imitation song style in the current printed font. In addition to the fonts similar to those in Song Dynasty, there are many fonts that imitate Zhao Mengfu's regular script, which are also artistic and standardized printing fonts, and some printing fonts are similar to regular script characters.
In the Ming Dynasty, the woodblock printing industry was unprecedentedly prosperous, and woodblock fonts were diversified. During the period of Qin Long and Wanli, many sculptors carved a font, commonly known as "skin outline character". This square, light and heavy font, eye-catching and easy to engrave, soon became popular. In order to distinguish it from other fonts at that time, booksellers called this font "pine nuts". In fact, this font is obviously different from the font in the Song version of the book. Why is it called "Song Style"? Because the Song version of the book is very precious in the Ming Dynasty, and even priced by pages, booksellers call this new font "Song Style" to improve the value of the book. The name Song Hippo Chef has always been used, which is the source of Song Hippo Chef in printed fonts.
As can be seen from the above, Song Ti is a printing font, which appeared in the mid-Ming Dynasty, while the font similar to Song Ti used in printing books in the Song Dynasty has existed since the early years of the Northern Song Dynasty, so Song Ti and Song Ti imitation have nothing to do with Qin Gui.
