Jiang Ruizhao

Biodata

Background / History

Jiang Ruizhao is a Tannan Normal University student who shares Dormitory 405 with Mu Changsheng and Xi Chunpeng. Described as the dorm's “gym rat,” he is over 1.7 meters tall and heavily muscled. Early on, he aligns himself with Song Haoning, joining Song in belittling Mu Changsheng's delivery work and ambition to become a rural teacher. 2

His hostility toward Mu escalates through repeated insults toward both Mu and Xi Chunpeng. He mocks Xi for accepting food from Mu, disparages Mu as poor, and reports the dormitory conflict to Song Haoning after being intimidated by Mu's changed physique and expensive phone. 13 14

Jiang begins dating Guo Xiaolan, but remains unaware that she is involved with Song Haoning. Mu deliberately plants doubt by showing him footage of Guo entering a BMW resembling Song's car; Jiang initially rejects the implication and defends her. 24 His suspicions deepen when Guo's overnight absence and inconsistent explanations fail to resolve his doubts. 25

He finally discovers intimate calls, messages, and photographs between Guo Xiaolan and Song Haoning while handling Song's phone. Devastated by the betrayal of both his girlfriend and his friend, he contacts Mu Changsheng from Binhe Park, apologizes for his past behavior, and asks for help. 28 29 Jiang thereafter pledges to follow Mu's lead and assists in plans against Song. 30
