A professional stunt double and actor who is the target of Yu Yan's recruitment for Twenty Years. He is described as notoriously stubborn and hard to recruit, compared to Zhuge Liang. He is trapped in an exploitative contract with Chen Hao because Chen Hao provides free dialysis treatment for Cao's mother who suffers from chronic kidney failure. He endured cold weather on set wearing only a thin, hole-filled sweater and was deliberately made to repeat scenes by Chen Hao. He briefly slowed down when passing Yu Yan but ultimately walked away without speaking.
