It can be seen from here that Fan Zeng was the first person to say this sentence. Although it was said by Nan Gong, a hermit of Chu, Fan Zeng may have used Nan Gong's words as an excuse. When Fan Zeng was a strategist in Chu State, it was normal for him to think of some inspiring slogans to inspire Chu soldiers. He told the soldiers: "Even if there are only three families left in Chu State, Qin State must be the death of Chu State." What's more, there are not only three clans left in Chu, so the destruction of Qin in Chu is just around the corner.
Who said that "although Chu has three households, Qin will die"? Why do people believe this?
Of course, many people think that the "three households" do not refer to specific figures, but symbolize the royal family of Chu. The surname of the Chu royal family is Mi, and this branch is Xiong, which was later divided into Zhao, Qu and Jing. So these "three households" are all the royal families of Chu. Although the Chu family was all slaughtered by the state of Qin, there are still many branches of the Chu royal family. As long as they don't die, they will have a chance to revive Chu and destroy Qin.
