他们是杀了杨国忠怕杨玉环报复，她也确实可能会报复，唐朝女儿是天然被归为父权这边不论出嫁否。当时那个情况确实无解，要怪就怪李隆基二十年不理朝政埋下的大雷吧，坑死全体国民了
They killed Yang, afraid of Yang Yu Gang's revenge, and her daughter was naturalized as a father, whether she was married or not. That was the case. Blame Li Lungi for ignoring the mines that had been laid in the DPRK for 20 years, killing the entire nation.
