Who can tell me what it means?

1, Shangjiuliu: emperors, sages, hermits, immortals, literati, warriors, agriculture, industry and commerce.

These people are people who live at the top of the pyramid. In the ancient feudal monarchy, the emperor was naturally supreme, the sage was very respectable, and the hermit was particularly talented and didn't like the worldly world of mortals. The most respected thing in ancient times was to study hard and get ahead through the imperial examination. Only in this way can people enter the ninth category.

2, the next nine streams: witches, prostitutes, immortals, thunderbolts, shaving heads, blowing hands, actors, street, selling sugar.

First-class wizard: As the name implies, it is a wizard. Ancient times were an era of feudal superstition, so people were generally feudal. If they have nothing to do, please ask someone to draw a sign at home to watch Feng Shui exorcise ghosts and eliminate disasters.

Second-rate prostitutes: prostitutes in the open and prostitutes in the dark. Prostitutes here refer to geisha. These women are singers, and this kind of place is usually a place where rich men and women come. Only these romantic literati can play with singing girls.

Third-rate gods: there are magic sticks in the northern region that specialize in jumping to cure diseases. The great gods mentioned now are all awesome in a certain industry.

Liu Bang: It's the people we often see, banging gongs at night and shouting, "It's dry, be careful with candles." They are called bellmen.

Fifth-rate shaving: In ancient times, hairdressers walked around the streets carrying bags to shave people's heads. There was no such facade.

Liu Liu Piper: When there are any weddings and funerals at home, I will invite these people to play and sing.

Seventh-rate performers: Ancient people looked down on performers, so it was despicable to do this industry. Actors who perform on the stage are not respected. In the eyes of all people, they are inferior.

Liu Ba Street: generally refers to those beggars' brothers.

Low sugar selling rate: this is a traditional handicraft, which is gradually lost. A sugar seller refers to a person who sells sugar. They can blow out all kinds of small animals with a little sugar, which is very popular with children.

The source of the upper and middle reaches and the lower ninth stream

There is a statement about the social class of "Nine Streams" in History of Arts and Literature of Han Dynasty, in which "Nine Streams" are used to describe academic schools such as Confucianism, Mohism, Taoism, Buddhism, miscellaneous, agriculture, Yin and Yang, and vertical and horizontal.

"96" was not a derogatory term at the beginning. "Liu" here refers to the school. In today's academic discourse, these schools can also be called certain beliefs, such as Freudianism, Existentialism and Neo-positivism in the West.

About the Tang Dynasty, three religions, Buddhism, Taoism and Confucianism, were formally formed. After that, people combined the three religions and nine streams into one, and there was the theory of three religions and nine streams. The theory of dividing social classes into upper, middle and lower classes is quite different from this kind of three religions and nine streams, and has been used in a wider range.
