How are spies selected?

Special service personnel in Western societies do not require special selection. They are semi-transparent and semi-open recruitment for the society. As long as you have professional skills and the department needs manpower, you can apply for the job with your resume. But the positions open to the public are mostly analysts, technicians and clerks who compile reports. Field personnel, such as those depicted in the movie, are secretly deployed from the military and then undergo targeted technical training. But this method saves money, because once the agent becomes familiar, he can no longer perform the task.

There are differences between Chinese spies and Western society. The first difference is that they are completely confidential. They are not open to the public, nor are they recruited from the public. There is no channel for the public to work in confidential units. In other words, if you are an ordinary person, you will be forever isolated from it.
