Observed an interesting phenomenon.

There are many street vendors near my home, close to the subway entrance and public rental housing.

The most homogenized service is hair cutting, where a lamp and a mirror are set up, generally serving workers from nearby construction sites and elderly residents of public rental housing.

Young people naturally wouldn't choose to get a haircut in such places.

The price is 10 yuan per person, and the haircut takes about 15-20 minutes.

In the past two months, there weren't many people setting up stalls. Sometimes when passing by at night, I often saw people getting haircuts.

Then there is the phenomenon that everyone enjoys, or perhaps the traditional virtue of our countrymen — the beginning of the internal competition.

The number of haircut stalls is increasing. It started with one or two fixed locations, and now there are stalls at the entrance of small parks and squares next to intersections... In short, wherever there is a slightly larger flow of people, there will be one or two stalls.

The price is naturally getting lower and lower. I just passed an intersection and found that the cheapest has already reached 7 yuan per person.

The most crucial thing is that there aren't many people cutting hair. I feel that each stall only serves two or three people in one night.

That is to say, most people can only earn twenty to thirty yuan in one night, working for five to six hours.

To be honest, I find it a bit hard to understand this approach and the phenomenon of involution.
