"The heart of Sima Zhao" comes from the Records of the Three Kingdoms, Book of Wei, Annals of the Duke of Gaoguixiang. The original sentence is, "The heart of Sima Zhao is known to every passerby," referring to the fact that during the Three Kingdoms period, Sima Zhao, a powerful minister of Wei, had an extremely obvious ambition to usurp the throne, so obvious that even ordinary people on the street knew it. Later, this idiom came to be used as a metaphor for someone whose hidden ambitions or schemes have been completely exposed and are known to everyone. Its deeper meaning lies in emphasizing that "the ambition is glaringly obvious," that is, the improper intention can no longer be concealed. It is mostly used in a derogatory sense, often in political, workplace, or competitive settings, to describe someone who openly or semi-openly seeks power, status, or personal gain, and whose intentions have already been seen through by everyone. In emotional coloring, it carries a tone of sarcasm, vigilance, and criticism. In terms of cultural background, it reflects ancient China's historical memory of powerful ministers usurping the throne, and also embodies the characteristic of Chinese idioms being good at using historical allusions to summarize complex human nature and political phenomena.
