Puyi was extremely unhappy with his life as a virtual prisoner in the Salt Tax Palace, and his moods became erratic, swinging from hours of passivity staring into space to indulging his sadism by having his servants beaten. The fact that the vast majority of Puyi's "loving subjects" hated him obsessed Puyi, and as Behr observed it was ""... the knowledge that he was an object of hatred and derision that drove Puyi to the brink of madness"". Puyi always had a strong cruel streak, and he imposed harsh "house rules" on his staff; servants were flogged in the basement for such offenses as "irresponsible conversations". The phrase "Take him downstairs" was much feared by Puyi's servants as he had at least one flogging performed a day, and everyone in the Salt Tax Palace was caned at one point or another except the Empress and Puyi's siblings and their spouses. Puyi's experience of widespread theft during his time in the Forbidden City led him to distrust his servants and he obsessively went over the account books for signs of fraud. To further torment his staff of about 100, Puyi drastically cut back on the food allocated for his staff, who suffered from hunger; Big Li told Behr that Puyi was attempting to make everyone as miserable as he was. Besides tormenting his staff, Puyi's life as Emperor was one of lethargy and passivity, which his ghostwriter Li Wenda called "a kind of living death" for him.
