Although Qin Gui is treacherous in being an official, his attainments in literature are still relatively high. He was able to enter the DPRK as an official because he successfully won the top prize and his calligraphy was particularly good. Song Huizong, the monarch of the Northern Song Dynasty at that time, was quite accomplished in literature, although he was mediocre at governing the country. Therefore, he was very fond of Qin Gui, who was well-read and versatile. Therefore, Qin Gui was promoted to the suggestion of Zuo Si of Yushitai by him, and was responsible for all kinds of official documents of Yushitai.
Because there was no uniform font in the Northern Song Dynasty, different people used different fonts to write official documents. In the process of dealing with official documents, Qin Gui often feels headache because of various fonts. At the same time, he also thinks that this is not standardized. So he based it on Song Huizong's? Thin and golden? A new font was cast and presented to the king. After reading it, Song Huizong thought this new font was really neat and beautiful, so he ordered all official documents to be written in this new font, and ordered people to promote this new font nationwide.
However, this new font was not named at that time. Later, as Qin Gui's reputation gradually deteriorated, people didn't want this new font to be associated with him. Therefore, in the end, the country name of the Song Dynasty was adopted to call this new font, that is, Song Dynasty, which later developed into imitation Song Dynasty. Today, this font is still in use and has a high usage rate.
