Maybe it's the problem of Heyuan education department. Children have not received a good education since childhood, but this is the case when they grow up.
Many educators in Heyuan do not meet the requirements. In other words, they teach bad people. Those who do education have no quality and can only teach such students. There are far more people who do bad things than those who are in charge of public security. Then, the social atmosphere is corrupt, and many things can be solved with money. Criminals can't stand punishment.
