Query: Who ruled after Guangxu?
Context: Rumors held that she or Yuan Shikai ordered trusted eunuchs to poison the Guangxu Emperor, and an autopsy conducted nearly a century later confirmed lethal levels of arsenic in his corpse. Puyi, the oldest son of Zaifeng, Prince Chun, and nephew to the childless Guangxu Emperor, was appointed successor at the age of two, leaving Zaifeng with the regency. This was followed by the dismissal of General Yuan Shikai from his former positions of power.
