It is said that some people have gray income. I want to know how they turn it into legal income. How can I find out that they have gray income?

Gray income, such as shopping cards issued by the unit, tobacco, alcohol and food, all count. Leaders of some key departments have great power, such as fire protection. There are Internet cafes and hotels that give out money on a regular basis. They have to give some during the holidays, and they have to give some when asking for help. This is gray income. Without the strong intervention of the procuratorate, it would be difficult to find out. A mayor's salary cannot afford to buy a Passat. You can understand that most people who can basically have private cars have gray income. Not just administrative units, many corporate leaders also have gray income. There are hospitals and schools.
