Regular script is also called regular script, real script and official script. It gradually evolved from official script, becoming more simplified and more horizontal and vertical. Ci Hai is interpreted as "square, straight and exemplary". This kind of Chinese character has the correct font and is a modern popular handwritten orthographic Chinese character.
Regular script is also the official name. There are 20 regular calligraphers and 18 regular calligraphers in the provincial history museum of New Tang Book. Regular script, as a formal name, is also called regular script player, who is in charge of calligraphy and writing, and is listed in the same institution because of the different specific division of labor. "Tongdian Official Twenty-two" records that the regular script writer is an outstanding official. There were no regular script players in Song Dynasty, only regular script.
