Dong Guo's girlfriend of two years. She initiated the breakup on Wednesday, which led to three days of arguing. Dong Guo went to her rented apartment, threatened suicide by jumping off the building, and ultimately jumped. She signed the surgical consent form on behalf of Dong Guo's parents after receiving authorization. She was later beaten by Dong Guo's father after the patient's death but did not call the police at the time, thinking the injury was not serious.
