Legal analysis: this is the confirmation that they have completed the task, that is, the superior asked them to distribute leaflets and preach. They have this responsibility. Their superiors should confirm their work and understand the situation of fraud prevention and law popularization among residents, so you are required to register briefly. It doesn't matter. When the other party comes to the door, they must show their certificates and warning signs. You just need to cooperate. Of course, it is not mandatory, but after all, people are kind and it doesn't matter if they sign something. But before signing, confirm the identity of the other party, and then confirm the content of the document (that is, the document you want to sign). After all the confirmation, if there are no other questions, just sign your name. In addition, the registration form may also include family members and education level, which is what the film police need to know. Unlike before, you had to register for a residence permit. Nowadays, many places are not so compulsory, which brings some difficulties to the work of film police. Perhaps they do this, but also a preliminary understanding of the state of life.
