I Am a Police Officer, and All the Aunts in the City Are Informants.

Pei Zheng, a detective known as a "mad dog" in the police community, acts violently and uses extreme methods. Because he was too unruly in handling the case, he was sent to Taiping Street, the shabbiest street, and became a small-scale policeman who caught cats and dogs. The provincial boss thought he would remain silent, but little did he know that Pei Zheng had directly opened the door to a new world! Don't have a Sky Eye system? Aunt Wang, who eats melon seeds at the entrance of the village, is the strongest living radar! No undercover informant? Uncle Li, who dances in the square, controls the city's underground intelligence! As a result, the entire police style completely changed. While mediating a dispute between mother-in-law and daughter-in-law, Pei Zheng uncovered a serial killer who had been absconding for ten years. An unlicensed vendor was investigated and a well-hidden transnational money laundering syndicate was overturned on the spot. When the provincial task force looked at the piles of "top secret files" being written off one by one, all the bosses were numb. The leader of the task force collapsed: "We have been investigating for half a month and there are no clues. You send a red envelope and the aunt takes out the suspect's underwear?" Pei Zheng blew out a smoke ring and said: "The eyes of heaven and earth are not as good as human eyes. I am just an ordinary police officer. I rely entirely on the support of the masses."
