"Success and failure both come from Xiao He" originates from the Records of the Grand Historian: Biographies of the Marquis of Huaiyin. It tells how Han Xin was recommended by Xiao He to Liu Bang and appointed as a great general, achieving great merit, and later was lured to his death through Xiao He's scheme. This idiom metaphorically describes how the success or failure, good or bad, of an affair is caused by the same person or the same factor, emphasizing the dual role of a key figure or factor. Its deeper meaning lies in revealing the complexity of human affairs and the unpredictability of fate: the same person can be both the driving force behind success and the driving force behind failure. It is mostly used to describe a situation in which someone or something plays a decisive role in the outcome, and the outcome may be either good or bad. In terms of cultural background, it reflects the wisdom of political strategy and the wise appointment of capable people in ancient China. Its emotional tone is relatively neutral or slightly reflective, often carrying a sense of helplessness and irony.
