In the traditional notation of ancient folk music in China

Taking "harmony, thinking, change, business, delay, fairness and model" as the name, it is the public deficit notation.

Miyachi notation is one of the traditional notation of Han nationality in China. It is named after writing the name of the volume with words such as labor and ruler. It originated in China during the Tang Dynasty, and later spread to Japanese, Vietnamese, Korean Peninsula, Ryukyu, China and other China cultural circles. It belongs to a character spectrum. It was widely circulated in ancient times, but today only the actors and learners of traditional Chinese opera still use Miyachi notation to sing or record music.

Modern Chinese orchestras have generally changed to simple music or staff. Traditionally, Gongchi symbols are written straight from right to left, just like words, and now they can also be written horizontally. Miyachi notation has a long history, and Le Yan's half-character notation was used in the Tang Dynasty. For example, in the late Tang Dynasty, the four-year (933) edition of Da Qupu of Tang Dynasty was discovered in the Thousand Buddha Cave in Dunhuang. In the Song Dynasty, it was a popular word spectrum, such as the spectrum recorded in Zhang Yan's Etymology, the side spectrum in Jiang Kui's Song of Taoist Baishi, and the tube chromatography in Chen's Shilin Guanglu. It developed into the palace pool spectrum prevailing in Ming and Qing Dynasties.
