The police, Zheng Hao and others went to Li Yong's house to investigate.With the help of Li Yong's wife and daughter, clues about Li Yong's traces were obtained. After the police interrogation of Li Yong, they finally figured out Bai Fuda's criminal methods.Bai Fuda adopted a more concealed method than Qi Ke to re-import the mobile phone and then package it for circulation and export again. Li Yong also identified that the person who traded with it was Zhao Mingda.

Subsequently, the police and the Inspection Bureau determined Zhao Mingda's whereabouts. After several research and discussion, they decided to set up controls of various traffic fortresses that may travel directly to Switzerland.With his understanding of Zhao Mingda over the years, Zheng Hao guessed that the itinerary to Switzerland was just his cover. The water route of Xindong did not directly reach ships in Shanghai, Beijing and other places, which was easy to become a visual blind spot for the police.
Sure enough, Zhao Mingda met Zheng Hao at the dock, and the law was wide and unobstructed, and Zhao Mingda was arrested.At this point, all relevant personnel from Qike Company and Baifuda Company's large-scale tax fraud case were arrested.A year later, the Inspection Bureau also welcomed a new group of tax officials. Xiong Yi, Li Xinxin, Gao Peng and others have grown into the backbone of the Tax Bureau after hardships.Zheng Hao and Li Dongjie remained at their posts and led the cadres of the Inspection Bureau to continue to fight on the front line of tax protection.
