As a proper name, “Puyi” isn't used in daily conversation like a regular word. Instead, he is referenced in specific contexts:
Historical Discussion: When discussing the fall of the Qing Dynasty, the Xinhai Revolution, or the Japanese occupation of Manchuria, his name is central.
Cultural References: People often refer to the film 《末代皇帝》 (Mòdài Huángdì), “The Last Emperor,” which has shaped the popular imagination of who he was, both in China and abroad.
Tourism: Tour guides at the Forbidden City in Beijing (his childhood home) and the Museum of the Imperial Palace of the Manchu State in Changchun (his palace as a puppet emperor) will constantly reference 溥仪 (Pǔyí).
Metaphorical Use: Occasionally, his name can be used metaphorically to describe a leader who is out of touch or presiding over the collapse of an institution. For example, one might jokingly call the CEO of a failing newspaper chain “the Puyi of the print media world.”
