|The daughter of Zheng Zu and younger sister of Shang-Chi, Shi-Hua was raised alongside her brother at their father's Hunan retreat. During their childhood, the two siblings accidentally entered one of their father's forbidden laboratories against his orders. As punishment, Zheng Zu burned a mark on Shi-Hua's forehead and sent her to the House of the Deadly Hammer in Russia while telling Shang-Chi he had her executed to teach him a lesson. Years later, Shi-Hua would eventually become the Champion of her House, only to be unfavorably compared to Shang-Chi by her father, making her resent her older brother.
|Following Zheng Zu's death, the leadership of the Five Weapons Society was passed on to his son, Brother Staff, who Shi-Hua killed to usurp control of the organization. Despite Zheng Zu's spirit selecting Shang-Chi over her for leadership, Shi-Hua named herself Supreme Commander and sent the Warriors of the Deadly Staff to kill her brother.
