citizens have the right to ask the police to show their police cards. Under normal circumstances, the police do not need to show their certificates when they wear uniforms, police titles and police numbers. They only need to declare and show their police officer's cards when they enforce the law in plain clothes. According to Article 34 of the Administrative Punishment Law: "If a law enforcement officer makes a decision on administrative punishment on the spot, he shall show his law enforcement identity certificate to the party concerned ..." Article 23 of the People's Police Law stipulates: "The people's police must dress in accordance with the regulations, wear the people's police logo or hold the people's police certificate, keep the police appearance neat and dignified." It can be seen that the Administrative Punishment Law requires law enforcement officers to show their identity documents when enforcing the law, while the People's Police Law stipulates that the police have two ways to show their identity when performing official duties: one is to dress in accordance with the regulations and wear the People's Police logo; Another way is to show the people's police certificate. The provisions of the Administrative Punishment Law and the People's Police Law on whether law enforcement officers should show their identity documents are inconsistent, but the People's Police Law is a special law. According to the legal principle that special law is superior to general law, the police should apply the provisions of the People's Police Law.
