She has been promoted in her position and is training police officers with her assistant A Sheng (played by Zhang Jianting) who has special functions.

Ah Xiong encountered a murder case at the hotel where he was staying, and was forced to stay by Sister Zheng who came to investigate the case. Uncle Wu, who was busy looking for Taiwanese spies, got acquainted with a group of swindlers. The abandoned Ah Xiong stayed at Sister Zheng's house to receive witness protection.
