The prototype of Chen Zhou in the Illustrated Book of Hunting Crimes is Du Shaoping.

Zhou Jun was admitted because of violence and wounding, and it was extremely difficult to find a job after he came out. But not only did he find it, he was also the librarian.

So, this is obviously because there is a certain person who helped Zhou Jun and arranged this job for Zhou Jun. And if nothing unexpected happens, this person is Chen Zhou, the head of Tongcheng Technology Company. This is not just because in the preview of episode 20, Chen Zhou revealed his true face. This is especially because there are two foreshadowings arranged in advance in the play.

Zhou Jun made his official appearance in the Hejian Library. At that time, Chen Zhou was giving a speech in the library, introducing his company's Silver Eagle system to a group of people.
