What is "dirty"?

The next three refer to three industries, namely foot rubbing, shaving and massage. Now it is the foot washing city hairdressing salon and bath center.

Also known as "the next three rotten". Refers to a cheap and worthless person.

In ancient times, there were three religions and nine streams, which made the third stream the last third stream: prostitutes (prostitutes), books (scholars) and beggars (beggars).

Source: "the next three rotten" comes from grinding.

It takes many cycles to grind flour by hand, and each cycle is called "rotten". The flour ground by the "first rotten" is rough, and the "second rotten" grinds out the essence of grain in large quantities. The flour ground after "two rotten" is collectively called "three rotten", which refers to the flour with poor quality. After referring to people.

From the first cycle to the third cycle, a lot of "top three rotten foods" appeared, and all the noodles are the kernel of whole grains, that is, the essence, with good quality. The rest of the "last three rotten" are mostly chaff or some broken skin, and the quality is obviously not as good as that of the "first three rotten", which is extended to "not a good thing" and "not a serious thing"

"Cheap" generally refers to bad and improper things and people.

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 "upper nine streams, middle nine streams and lower nine streams" was derived. It should be noted that this method of dividing people is the dregs of feudal thought, even in ancient times, it was only a universal culture and was not respected by the mainstream literati class.

Basically, it can be summarized as: first-class actor, second-class pusher, third-class tortoise, fourth-class tortoise, five shaved heads, six back rubs, seven prostitutes, eight thieves and nine soot blowers (hookah vendors).

Shangjiuliu: First-rate Buddha (Sakyamuni), second-rate immortal (Yuanshi Tianzun, Taishang Laojun, Eight Immortals, etc. ), the third-rate emperor (the real dragon emperor and feudal emperor), the fourth-rate official (the big and small official), the fifth-rate cooking pot (the winery, once the biggest manufacturer in feudal times), the sixth-rate pawn (the pawn shop), the seven merchants (the merchants), the eight guests (the manor owner) and the nine Zhuang fields. This statement seems to be influenced by Taoist pastoral taste)

Zhong Jiuliu: First-class doctor (doctor, doctor, pharmacist), third-class feng shui (Mr. Feng Shui, yin and yang teacher), fourth-class batch (batch of eight characters, fortune telling), fifth-class painter (calligraphy and painting), sixth-class physiognomy (physiognomy, fortune telling), seven monks (monks) and eight Taoist priests (guqin chess).

Xia Jiuliu: First-rate wizards (southern wizards who draw spells to attract gods to exorcise ghosts), second-rate prostitutes (prostitutes in secret), third-rate gods (wizards possessed by immortals who treat diseases in the form of dancing), fourth-rate bangzi (night watchman), fifth-rate hairdressers (barbers who carry burdens everywhere), sixth-rate trumpeters (trumpeters), and seventh-rate performers (each)

Of course, literally, the combination of the three "nine streams" of the upper, middle and lower levels is the 39777 line, but in fact, it is not, even the 72 lines are included, because the name of each first-class industry contains many professions of peers or similar peers, such as "shaving hair" of the fifth stream of the lower stream, as well as pedicure, running errands, pulling carts, massage, shop assistants, dancers, helping others and so on.
