Regular script, also known as real script and official script. China's calligraphy is divided into "seal script, official script, regular script, running script and cursive script", and regular script evolved from official script. Regular script in a broad sense includes Weibei, and regular script in a narrow sense refers to Tang script. It was in the Tang Dynasty that the strict standard of regular script was established, and its fundamental rule has been passed down to this day.
Since the early Tang Dynasty, the official script was first renamed as Bafen, and the latter Bafen was mixed with the official script to form the official script. It was not until the middle Tang Dynasty that the official script was restored to its original name, but it was gone.
In fact, one of the officials said that it could include eight points and official documents. For example, Yang Xin's "Cai" refers to some good "Li, Cao" or "Cao, Li" below the Eastern Jin Dynasty and Wang Xizhi, and refers to cursive script and official script. Another example is what Tang Sun said in the Preface to Book Spectrum, "Yuan Chang specializes in official books", which means the eight-point method.
Eight points is also called official script, and the name has not been cancelled (also renamed) until it died. Zhengshu finally got rid of the official name completely. About the Northern Song Dynasty, it was renamed regular script.
Eight points, official books can be collectively referred to as official books, as mentioned above, but official books in Qin and Han Dynasties cannot be called eight points or official books. At first, this problem caused some confusion in Liang Gengshouwu's On Calligraphy. For example, he said, "What Cheng Miao did ... is called official script, and so is official script now." What he really means is that the official script at that time can also be called official script, but the tone is vague, which makes people mistakenly think that official script can also be called official script. In the Tang Dynasty, Zhang Huaiguan's Shuduan and Lishu Preface aggravated this confusion. On the premise of admitting that Cheng Miao compiled an ancient (Qin and Han) official script, he also wrote some workers from Jin Dynasty to Tang Dynasty as official scripts. They all became descendants of ancient (Qin and Han dynasties) officials under Cheng Miao's name. He did not distinguish between ancient (Qin and Han) officials and modern officials. This is why all the officials in ancient times (Qin and Han Dynasties) changed their names to eight points in the Tang Dynasty, and then one point was completely given to the official book.
As early as the Western Han Dynasty, Lishu was called a real book. For example, in the "Three Wangs' Family" in Historical Records, Chu said that "Two Grass True Books", "The Book of the Later Han Dynasty" and "Dong Si's Wife (Cai Yan)" also had the language of "True Grass Obedience". Although there was an eight-point method at that time, I estimate that this "truth" still refers to the ancient official style. Later, Liu Shao of Jin Dynasty also said "seeking for grass and harmony" in Flying White Book, and when talking about the calligraphy styles of Zhong and Zhang in the preface to Book Spectrum of Tang Sun, he also said: "Imitating grass is more true than growing grass is more true". The "truth" there may have been divided into 1 18 chapters in the articles of association, because time and time are different. As Sima Yu, a Jian Wendi in the Jin Dynasty, said in "Answering Wang Xizhi's Book on the King of Eastern Hunan": "You can get all kinds of grass." Also, when Tang Li Simiao discussed Yu Shinan's calligraphy in Book Back, he quoted Cai Yan's words of "true grass is obedient", which were all called official books. This shows that what they call true books, that is to say, "orthography", can include all positive books and eight-point positive books, unlike later generations, which only changed the positive books into real books.
Regular script means regular script, which was first mentioned in Zhang Huaiguan's Shu Duan. In the Han dynasty, it was also another name for "regular Chinese characters", which was still used by people in the Six Dynasties. For example, Yang Xin's Cai and Lun Shu all said in Biography of Wei Shengshou: "Birth characters are good at regular script." That's the abbreviation of "eight-block method", which didn't replace the name of the official book until the Northern Song Dynasty, and its content was obviously different from the ancient name. There is probably an example of the above. If these concepts are not clear, they will inevitably confuse other aspects forever, which is useless.
