In ancient times, social strata were divided into nine grades according to the level of nobility and inferiority. Later, with the complexity of social division of labor, the saying of nine streams in the upper class, nine streams in the middle class and nine streams in the lower class was derived. Prostitutes and slaves belong to the lower classes.

Ancient hierarchical division

Ancient folks divided Jianghu people into upper and lower classes;

Shangjiuliu: Monks, Taoist priests, painters, practitioners, geomancers, fortune tellers, Mr. Xue, pharmacies;

Dirty people: actresses, maids, prostitutes, beggars, villains, hairdressers, pawnbrokers, kitchen chefs, bathhouses, carpenters.

The reason why the first nine kinds of people enter the upper class seems to lie not in how noble their status is, but in their frequent contact with the upper class and a little light.

Another way is to classify all people in society, so there are three streams:

Shangjiuliu: emperors, sages, hermits, children's immortals, literati, warriors, farmers, workers and businessmen.

Zhong Jiuliu: Ju Zi, Doctor, Xiang Ming, Dan Qing (painter), scholar, monk, Tao, Ni.

Dirty people: master, servant, scale (scale), matchmaker, pawn, time demon (kidnapper, witch), thief, thief and prostitute.
