What do you mean by the lower class?

And "low income" refers to: teachers, officials, scales, matchmakers, pawns, demons, thieves, high platforms, flute playing, circus, pushers, pools, back rubbing, repairs, matches, prostitutes, dog beating, pedicures, haircuts, vegetable lifting, tailors, actors, drummers and wizards.

In ancient China, there were nine occupations. More complicated are the upper nine streams, the middle nine streams and the lower nine streams.

Ancient folks divided Jianghu people into upper and lower classes;

Shangjiuliu: Monks, Taoist priests, painters, practitioners, geomancers, fortune tellers, chefs, private school teachers and pharmacies;

Dirty people: actresses, maids, prostitutes, beggars, villains, hairdressers, pawnbrokers, bathhouses and 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.
