Why are only primary school students innocent？

　　Liangzhou District, Wuwei City, Gansu Province, made a "strange trick" in the written examination of the public security system in the whole district, and asked 18 local young pioneers to invigilate. As a result, these children caught 25 cheaters. Small invigilators can catch 25 cheaters. Of course, it doesn’t mean that they can see more clearly than big invigilators. They are just not contaminated with the bad habit of "turning a blind eye". Only by starting from the system and relying on temporary innocence can we fundamentally solve the problem. Pupils’ invigilation to catch cheaters is like the whole officialdom. Some things children can do, just to see if "invigilation" turns a blind eye.
