"Three Jade" is a story in the Romance of the Three Kingdoms written by Luo Guanzhong in the Ming Dynasty. It tells the stories of "The 51st time Coss fought against the soldier Kongming in Zhou Gongjin" and "The 55th time when Xuande inspired Mrs Sun".
Zhuge Liang saw through Zhou Yu's three schemes, namely, "Kongming took his anger out on Zhou Gongjin" and "The 56th Cao Cao banquet, Kongming took his anger out on Zhou Gongjin".
This story was invented by Luo Guanzhong to beautify Zhuge Liang, and there is no such story in official history. In addition, Zhou Yu is also very broad-minded, which is completely different from that described in The Romance of the Three Kingdoms.
