Zhang Qian is a beautiful young policewoman who graduated from the Police Academy two years ago. She comes from a high‑profile family (father is deputy head of the Municipal Committee, mother a professor, brother an army officer, uncle and aunt run a company). She insisted on working in criminal investigation despite her family’s wishes. She has a fiery and stubborn personality, hates evil, and is a staunch materialist who initially opposes inviting a “charlatan” to help. She is assigned by Captain He to accompany Chen Cheng and must obey his three conditions: absolute obedience, no questions while working, and she must not interfere. She argues with Chen Cheng constantly, calling him a “charlatan” and a “bastard”. She wears Chanel lavender perfume (mistaken by Chen for osmanthus). She carries a Type 54 police handgun for the mission. After witnessing the supernatural appearance of Cao Jiaoer’s spirit, her worldview is shaken. She is dedicated to solving the case, feels the pressure, and eventually respects Chen Cheng’s abilities. She has a tsundere attitude and often blushes when teased.
