"Sitting on a mountain to watch two tigers fight" literally means sitting on a mountain watching two tigers fight. It is a metaphor for adopting a spectator's attitude in a conflict between two or more parties, not intervening, and waiting for an opportunity to profit from it. Its core lies in the contrast between "watching" and "fighting": oneself stays out of the matter and keeps a safe distance, while others fall into fierce conflict. This idiom is often used to describe a strategic posture of standing by in politics, business, or interpersonal competition, with a somewhat neutral or even derogatory tone, suggesting that the onlooker may have ulterior motives and intend to reap the spoils. In terms of cultural background, it originates from the story in the Records of the Grand Historian in which Chen Zhen advised King Hui of Qin. Chen Zhen used the analogy of "two tigers fighting over a man" and suggested that King Hui of Qin wait for the two tigers to fight, and after one died and the other was wounded, then make his move. It is mostly used in scenarios such as analyzing the pattern of competition, reminding others to be wary of a third party benefiting, or presenting oneself as not participating in disputes. Emotionally, it can embody calmness and wisdom, but can also imply cunning and opportunism.
