The first one is a salesman. Many people actually don't understand what to be proud of, especially in the era of customer first. It seems miserable to be a salesman who smiles at people and is scolded. But the salespeople in the 1980s were different, because the reform and opening up had just begun at that time, so many things were valuable and worthless. So the shop assistants are so indifferent to people, and some even call names.
The second so-called "bad street" occupation is a driver. Nowadays, there are cars everywhere in the street, and big cars, small cars and even electric cars can jam the daily commute. But in the 1980s, driving was really a rare occupation. Not only is it difficult to buy a car, but you can't just get a driver's license. You must have a certificate from your company. Therefore, in the 1980s, if you were a driver, it meant that you were a "public servant" and naturally respected.
The third is the announcer. At that time, there were not so many TV programs and not many TVs to sell. It would be great if someone had a radio, and the announcer was born accordingly. The fourth type is basically gone now, and it may still be seen in remote villages, that is, film projectionists. In rural areas in the 1980s, people often took movie projectors to the threshing floor or open space to show movies. At that time, every family, old and young, would come out to watch movies, which was an empty alley. Unfortunately, with the development of science, movies have entered cinemas and computers, and this kind of scene is almost invisible.
