What incredible ways of making money have you seen or heard of?

Shaving master. Everyone knows that it is impartial, but it is certainly not easy to find it by yourself in a strange and slightly larger city. There are few young people to take over, so this is a dying industry. There is a simple reason. Not making money. First there were people who shaved their heads and carried their loads, and later they all became barbershops; In old Hong Kong dramas, you may see that some barbershops have hairdressers, but they are all masters. In fact, there are some old bathhouses in the mainland, and the new bathhouses are basically gone. The price is around 5- 10 yuan, which is similar to the price of shoeshine, and may be slightly higher. In fact, shaving is a delicate job. For example, people who shave with a three-layer blade every day can't feel it if they go to the master for two days. Of course, it's not just shaving, eyebrows, nose hair, but also picking ears with good service. Apply oil or foam to your face first, and then apply snow clam cream after shaving. The time is about 15-20 minutes. I feel that it is basically difficult to enjoy this service in 10 years. You can't buy it for 50 yuan.
