In ancient times, there were five tones: Gong, Shang, Jiao, Zheng and Yu, each of which had its own correspondence. "The public is the king, the business is the minister, Jiao Weimin, Zheng is the thing, and Yu is the thing." Later generations even compared public, business, communication, politics and Henan with spring, summer, autumn and winter and middle school. Let's start with the palace. Song Peiqi's Collection of Historical Records quoted Wang Su, a great scholar in the Eastern Han Dynasty, as saying: "The center is always square; Sima Zhen's Index of Historical Records of the Tang Dynasty said: "The square is the middle, the palace string is the largest, and it is eighty silk, so it is king." Zhang Shoujie's "Historical Records of Justice" said: "The palace belongs to the earth and lives in the center. It has four directions and is also a monarch." Regarding Shang, Wang Su said: "Autumn is the end of righteousness." Sima Yi said, "Business is gold, gold is decision-making, and ministers are also ministers. The string is seventy-two silk, and the second palace is like a minister. " Regarding the horn, Wang Su said, "Spring and things coexist, each with its own differences, and people are like it." Sima Zhen said: "The string is sixty-four silk, and the sound is among the palace feathers. It is not as good as jun, but better than things, so the clouds are clear and turbid, and people are like it." Zhang Shoujie's "Historical Records of Justice" said: "The horn belongs to wood, and its purity is the image of the people." Regarding the levy, Wang Su said: "Summer is full of things and stories." Sima Yi said, "The levy belongs to the summer, and the summer is long. Everything is tangible, everything has its own body, so it matches. Fifty-four strings are used for the string. " Zhang Shoujie's "Justice in Historical Records" said: "The matter of levying Ming is like fire." Regarding feathers, Wang Su said: "Things gather in winter", and Sima Zhen said: "Feathers are the clearest water and the image of things." Wang Su also said: "Things gather in winter, so things are called things, and the string is forty-eight silk." Zhang Shoujie's "Justice in Historical Records" said: "The monarch, the minister, the people, things and things have their own uses. Without conflict, the five tones are invincible." The five tones fully reflect the difference between monarch and minister.
