Cousin, hello!

Sichuan female police officer Sister Zheng (played by Zheng Yuling) is responsible for going to Hong Kong to capture escaped suspects and has to cooperate with the Hong Kong police. Police Chief Wu Weiguo (played by Tony Leung Ka Fai) is responsible for reception and cooperation in the investigation. He is confused by the naive and simple Sister Zheng and her assistant A Sheng (played by Zhang Jianting) who have arrived in Hong Kong for the first time. Due to regional cultural differences, Sister Zheng and Wu Weiguo continued to have frictions and conflicts, allowing the suspect to take advantage of and escape many times. Because she was attacked by a suspect in the hotel, the inspector arranged for Sister Zheng to stay in Wu Wei's country. The father of Wu Weiguo was the platoon leader of the 72nd Division of the Kuomintang Army. Due to their different beliefs, Sister Zheng had an incompatible relationship with Father Wu as soon as she arrived home. A series of hilarious confrontations unfolded, and strangely, the relationship between Sister Zheng and Wu Weiguo also slowly changed...
