This situation is also quite common in cities with a long history. There are many dialects in Shaanxi. Among them, in Guanzhong dialect, the word "thief" is definitely not a noun thief, but a modal particle to express dissatisfaction and exclamation, but initially as a verb to refer to theft and other acts. Of course, the original meaning of thief is still used in words, but in the semantics of Guanzhong people, this word can not be said casually. Similarly, "Qi" is a different word. In ancient times, this word represented noble morality. Now, if Guanzhong people say this word, they are cursing. It should be said that at first, this word was used to satirize some people with bad behavior or moral quality, and later it evolved into a special word for swearing.
"Don't rape and don't do business" dedicated to businessmen has a similar experience. In the early years, the status of businessmen was very low. In order to survive, when doing business, businessmen need to pay enough. When buying and selling food, it is not enough to fill the container with food, but also to fill the food with tips, so that guests feel that they spend less money and buy more things. Therefore, there is a saying "no point, no business", which means that if buying and selling can't maximize the benefits for the guests, don't go. But later, it lost a little weight and was misinformed as "no rape, no business"
Fortunately, a few slang words in the brothel have not been vilified at all, and even become taller. For example, when the property market opens, the stock market opens, and all elite rich people actively wait and see, tell each other, open, open! In fact, in brothels, opening the market means starting to receive customers. Remember when someone praised the beauty of a woman as "gorgeous"? The opening ceremony is a ceremony where guests uncover the gauze on the girl's face in the brothel to see if that face is pleasing to the eye and choose one they like best to take away. Later, it expanded to various entertainment activities, such as song and dance banquets. At first, it would say "opening".
There is also a slang term called "job-hopping", which means that the customer is tired of a certain woman and asks for a replacement. When changing, he can't embarrass girls, just say that he wants to leave. This is called "job-hopping". Of course, job-hopping is very neutral now. I won't say that you like the new and hate the old, and you are heartless scum. Of course, some bosses who just want to extract labor and don't want to give money will still scold their employees for being heartless and ungrateful. This kind of boss will be happy to jump ship early.
The third slang is "out". Now when we talk about it, we mean that we are not qualified to participate in the competition and are not qualified to advance. It's a very serious word, but in a brothel, out means that a woman can be taken out to play by prostitutes, and she can go back to the brothel that night or stay outside for a few days. This situation is called out. In fact, there are still many slang words in various industries. If we analyze it carefully, there are more interesting things in it. With the change of time, the degree of civilization development and the context of slang words are also changing. When we enter the ordinary society, slang words have become superficial words that everyone can understand.
