Advanced Usage
  • This idiom is primarily used in formal, literary, or historical contexts to describe strategic and total victories in politics, business, or competition. It emphasizes a decisive and overt change of power or loyalty.
Historical Origin
  • The idiom comes from the "Han Xin" story in Chinese history. General Han Xin, serving Liu Bang (founder of the Han Dynasty), used a clever tactic to defeat the larger Zhao army. Part of his strategy involved having his troops replace the Zhao army's flags with the red flags of Han after a surprise attack, causing confusion and collapse among the Zhao forces. Thus, "dựng cờ nước Hán" commemorates this act of symbolic conquest.
