The Iron Gang was a Chinese crime organization who had made enemies of the Ten Rings and their leader, Wenwu. Some time after Wenwu had left his criminal past behind and settled as a family man, the Iron Gang tracked him down to seek vengeance. Wenwu was away, so the Iron Gang confronted his wife Ying Li. Unable to talk them down, she sent her children away and faced the attackers. Without her powers, she was eventually overwhelmed and succumbed to her injuries. Seeking revenge on those who had taken his wife from him, Wenwu took up the Ten Rings again and proceeded to kill off all but the leader of the Iron Gang. Wenwu subsequently raised his son Shang-Chi to become a deadly assassin, and after years of training he was sent to America, where he killed the Iron Gang's leader.
