Why do Nanjing often recruit auxiliary police?

The population is huge, and the mobility of auxiliary police is too great.

1. Because Nanjing has a huge population, the people's police on the job can't fully undertake such a huge workload, and the auxiliary police have become a factor to help the people's public security maintain social stability.

2. Public security organs recruit auxiliary police to make up for the lack of police force. However, due to many problems and limited stability of the auxiliary police, the reality that the auxiliary police can't keep people is objectively caused. Every year, a large number of auxiliary police officers resign and have to be recruited again.
