Furthermore, according to the practice of China's calligraphy, all previous dynasties named fonts after the surname of the founder or representative. For example, Liu Gongquan's name is Liu Ti and Yan Zhenqing's name is Yan Ti, so the font created by Qin Gui should be called Qin Ti. In this regard, there is a saying: after Qin Gui became the prime minister of the Southern Song Dynasty, he linked with foreign countries, framed Zhongliang, and killed Yue Fei, a national hero who resisted the Jin Dynasty, on the charge of "unwarranted", which was despised by future generations and regarded as a sinner through the ages; To this day, the iron statues of him and his wife are still kneeling in front of Yue Fei's tomb and being spurned. During his 19 years in power, his reputation was very bad. He suppressed generals who resisted gold, betrayed the country and sought protection. People hate his behavior, and his fonts are not named after surnames. (Although the name "Qin Ti" really appeared when this style was just created, when Qin Gui was imprisoned, it was extremely rejected by the people and changed to the word "Song Ti".
In addition, calligraphers pay equal attention to morality and brushwork; Qin Gui, however, is insidious and cunning, has no big mind and high conduct, and even if the brushwork is beautiful, he is not happy; Therefore, the folk and calligraphy circles at that time did not want to associate this font with Qin Gui, so they changed it to "Song Style" under the name of the word-making dynasty and passed it down. Later, people imitated the structure and brushwork of "Song Ziti" and changed it into beautiful slender prints with the same thickness, which became the later "Song Ziti Imitation". "Imitating Song Style" is often used to print classical poems and literary masterpieces because of its straight strokes, clear lines and elegant figure. Later, it was designated as the standard font for mechanical drawing by the state, and was selected as the font by Chinese typewriters to become the font for printing documents.
With the development of cultural undertakings, for hundreds of years, on the basis of Songti characters, many variants such as Long Song and Ping Song have been derived. These new fonts were born to meet the needs of block printing and traditional movable type printing.
