One refers to regular script in a broad sense, that is, words with statutes that can be used as models. Model refers to the model. In the Tang Dynasty, Zhang Huaiguan said "eight points" in the Book End, that is, the so-called regular script, the method of folio is also, the form is also, and the model is also. Confucius said: this world is the next, thinking it is a model. So anyone who has statutes can be called regular script. This concept is a bit like swimming freestyle, freedom, that is, any way can be used. Regular script can be used as a model of calligraphy, which can generally be called regular script, so before the formation of regular script in a narrow sense.
The seal script and official script in the Western Han Dynasty can also be called regular script, so later regular script in a narrow sense was also called regular script or official script. In the Qing Dynasty, Liu Xizai's Book Outline, Volume 5, contained: "The paragraph has no name, not just an official book. Han Beihai's history of respecting the king, which the world thinks is Kai, is actually Da Zhuan. Wei Huan's "Book Potential" says that "Wang Ci-zhong initiated the practice of Buddhism", which is divided into eight parts. Some people also say that' Boying's writing style must be a model' and it is also a model. " Therefore, regular script in a broad sense can be used as a model calligraphy.
Secondly, it is our regular script in today's sense, also known as real script and official script. In ancient times, it was also called Kaili or Jinli. It can be seen from some calligraphy books of past dynasties (not to list them one by one) that regular script evolved from official script and official script. According to the law of profit and loss due to reform, it is obvious that regular script has evolved from official script to official script. From the wooden slips of Han and Jin dynasties, it is found that those fonts and brushwork have gradually taken shape in official script.
