853 starts with the public security bureau.

It's a fraudulent phone call, and 853 is the international code of Macao. The Macao police have no right to control mainland residents, so it must be similar to the fake of the mainland public security bureau, and it starts with 852 in Hong Kong, all of which are fraudulent phones. Affected by telecom fraud, many people are suspicious or even hostile to those who call themselves policemen on the phone. This has caused great difficulties to many investigators, including me. Of course, we think this shows that the people's safety awareness is improving, which is indeed a good thing, but sometimes many people miss the opportunity to recover their losses because they lack the ability to judge whether the other party is a real public security officer. First of all, you should think about whether you have been involved in anything that will come into contact with justice. For example, you have been infringed illegally, or you are not sure whether it is illegal in an economic dispute with others, or you don't know the source of the other party's money in a loan. Then check each other's identity. Generally speaking, the real police will contact you by phone and report to their own work units. At present, the municipal public security bureau has police corps, such as criminal investigation corps and economic investigation corps, and the provincial public security department has police stations or corps, such as criminal investigation bureau and economic investigation bureau. There are detachments under the corps and sub-bureaus. The municipal bureau under the provincial public security department and the sub-bureaus and district bureaus under the municipal public security bureau have police detachments, and the district public security bureau under the provincial city and the county public security bureau under the provincial city have police brigades. The real police must be standardized when reporting the name of the unit. In short, don't blindly think that all the calls you receive from claiming to be police are fraud. Calm judgment will not only help to recover their own losses, but also provide some convenience for investigators.
