Meaning of Tosagupeng (Tosa-gu-paeng)

1. 1. A Deep Dive into the Meaning and Historical Origins of Tosagupeng

2. Key Points

Today we will take a detailed look at the meaning of Tosagupeng (토사구팽). This expression frequently appears in news and various media, and we often see it used to describe situations where someone is treated as extremely important when needed, but then callously discarded once their usefulness has run out. The word "paeng" (팽), meaning to be cast aside, is said to derive from this very idiom, Tosagupeng. Tosagupeng is a four-character idiom (成語, chengyu) originating from Chinese classics. It is composed of four Chinese characters: 兎 (rabbit), 死 (death), 拘 (dog), and 烹 (to boil). Literally translated, it means "once the rabbit hunt is over (once the rabbit is dead), the hunting dog is cooked"—a strikingly cold metaphor for human reality. As mentioned, it describes the act of valuing someone highly when they are useful, then discarding them without a second thought once they are no longer needed. The origins of Tosagupeng trace back to the Spring and Autumn and Warring States period in ancient China. It is said to derive from the story of Fan Li (範蠡) recorded in the "Annals of King Goujian of Yue" in Sima Qian's historical work, Records of the Grand Historian (史記). Fan Li was a brilliant strategist who served as a close advisor to King Goujian of Yue, and he is known to have served the king with wholehearted loyalty and dedication. At one point, Fuchai, the king of the state of Wu, launched a massive invasion to avenge his father He Lu, bringing the state of Yue to the brink of destruction. King Goujian, filled with self-reproach, attempted to take his own life, but his loyal ministers Fan Li and Wen Zhong devised a meticulous plan to save Yue, dramatically reversing the situation and ultimately succeeding in bringing about the downfall of Wu. During this process, another famous idiom emerged—Woxin Changdan (臥薪嘗膽), which refers to Goujian sleeping on firewood and tasting bile to keep the memory of his humiliation alive and fuel his resolve for revenge. Having brought Wu to ruin, Goujian then gathered with the lords of the Central Plains, took oaths, and rose once again to the position of hegemon (覇者). Fan Li, having accurately assessed Goujian's character, described him as "someone with whom one can share hardship but not glory," and

fled from Goujian, going into hiding in the state of Qi. He sent a letter of warning to his fellow comrade Wen Zhong, who had endured the same hardships alongside him. The famous warning read: "When the birds are all gone, the fine bow is put away; when the cunning hare is dead, the hunting dog is cooked (飛鳥盡 良弓藏 狡兔死 走狗烹)." However, Wen Zhong ignored this warning and was ultimately put to death by Goujian.
