Does Tianjin police require a signature when they visit to promote fraud?

Tianjin police come to your door to promote fraud, don’t sign. In order to effectively improve the anti-fraud awareness of the people in the jurisdiction. The police will organize civilian and auxiliary police officers to carry out anti-fraud publicity and home visits in the jurisdiction on many occasions. Before the event, the police station made careful preparations and printed promotional posters and leaflets in advance. During the activity, civilians and auxiliary policemen carried promotional materials and went upstairs to each community one by one to promote the campaign. They distributed anti-fraud leaflets to residents. They patiently introduced all kinds of fraud knowledge to the masses in easy-to-understand language, and guided the masses on how to deal with fraud. Do not be gullible, greedy, or blindly obedient in life, and post anti-fraud reminder posters in prominent places in each community for people coming and going to watch and understand.
