How many kinds of police are there in China?

At present, the national police are divided into four categories. First, law and order. Two: judicial police. Three: Guoan. Four: armed police. Among them, public security police are divided into public security, traffic police, criminal police, drug control, railway, civil aviation and so on. These types of police are familiar to everyone. However, in 20 19, a new type of police, the exit-entry management police, was added on the basis of the original public security frontier armed police, and its duties and tasks were very diverse. At present, they are known to be responsible for border control, entry and exit documents handling, border security management, household registration management and so on. After the reform, the armed police force is divided into guard forces, and the active service system is the same as before. Guoan is a mysterious alarm, which is mainly responsible for detecting espionage cases that endanger national security. Judicial police are courts and procuratorates. The alarm numbers of prison guards and judicial police are seven digits, and the alarm numbers of other police types are six digits. The official alarm number is pure numbers, and the auxiliary police with letters in front of the alarm number, such as ZA, JF。 FJ, wait. I hope my answer can help you, thank you.
